When You’re Pontus Hultén They Let You Do It

Being Pontus Hultén must have been absolutely amazing, the king of all he surveyed. He was the founding director of at least three modern art museums and one of the most influential figures in 20th century art. A groundbreaking curator, a friend to major artists, and a stone cold crook.

Hultén made the first re-creation of Tatlin’s lost Memorial to the Third International for an exhibition at the Moderna Museet, which, great.

With permission from Duchamp, Hultén made exhibition copies of Duchamp sculptures, including the first copy of the Large Glass, for the Moderna Museet in 1961, which Duchamp signed as recognized copies on his visit to Sweden. No problem, but watch this space.

In 1968 Hultén bought hundreds of actual cardboard Brillo boxes, from Brillo, for a Warhol exhibition, and had a few made of wood in Stockholm, maybe 10-12, and not more than 15, with, if not Warhol’s permission, then his awareness. OK.

More power to the Danish Banksy dealer who got Marian Goodman’s domain name, and who is holding out hope that he can recoup on this Pontus Hultén Malmö Type Brillo Box. Hang in there, Hultén may turn out not to be a crook!

But then in 1990, after Warhol’s death, Hultén had 105 more Brillo boxes made in Malmö, which he said were made in Stockholm in 1968. He donated or sold these boxes all over the place until his death in 2006, based entirely on his association with Warhol, and his own assertions of authority. He sold 40 to Duchamp dealer Ronny van de Velde with certificates of authenticity saying they were from 1968. But Warhol never authorized these, and he definitely didn’t do it after he was dead. It turns out many people in the Swedish modern art world knew Hultén’s Brillo racket. Not OK.

An entire investigation and report on the various fabrications of Brillo boxes was conducted by the Warhol Foundation in 2010, which declared all the Hultén boxes to be Hulténs, not Warhols. (This, after Hultén got the Warhol Authentication Board to approve and add 94 1968-I-mean-1990 Stockholm/Malmö boxes to the catalogue raisonné in 2004.) Shady, a bummer for a few collectors, but kind of hilarious.

a torn fragment of a grimy envelope from 1920 has a sketch of four corner elements coming together at a cross intersection, with what look like pins or screws holding each arm together. in french is written haut bas, av., arr., top, bottom, front, and back. this diagram by marcel duchamp was stolen by museum director pontus hulten in 1960, and recovered in 2018
up, down, front, back: Duchamp’s 1920 sketch for Rotary Glass Plates, jacked by Pontus Hultén in 1960 from Yale University Art Gallery.

But in 1960 Pontus Hultén also straight-up stole at least four Duchamp drawings from Yale University Art Gallery. Katherine Dreier had donated Duchamp’s 1920 sculpture Rotary Glass Plates to Yale in 1941 as part of the Société Anonyme. Hultén visited the sculpture for what Yale’s extraordinary provenance note for this sketch on an envelope of the Rotary Glass Plates says was to consider it “for inclusion in an exhibition.”

What he was doing was studying how to refabricate it. The 1961 exhibition, Movement in Art, for which Hultén and Ulf Linde fabricated all the Moderna Museet’s Duchamps, including a Rotary Glass Plates. [Actually, Linde made the Large Glass; Hultén made Rotary Glass Plates with Per Olof Ultvedt and Magnus Wibom.]

in a warmly lit gallery at yale, a white woman behind a stanchion with her hair pulled back like a soccer player leans down to align her vision with the axle of marcel duchamp's sculpture where five spinning glass plates create the optical illusion of concentric circles. the x-based apparatus has a motor at back. the axle is supported at eye level for a shorter person. duchamp made this in 1920, and katherine dreier donated it to yale in 1941. it is rarely turned on, though, and perhaps the man in front of the stanchion in this photo, wearing an all dark suit, is one of the yale engineering professors who restored the sculpture in 1999. a crowd in the background is perhaps waiting for this white lady to finish so they can take a turn.
After some engineering professors restored it in 1999, Yale turned on Rotary Glass Plates for a two-day Duchamp/Johns symposium in 2000. image: Yale Bulletin

Yale writes that “Hultén reportedly removed the sketch, along with three others, from the artwork’s storage box.” I think it illustrates how to clamp the painted glass plates to the central axle on which they rotate. Hultén apparently gave the sketch to Linde as a birthday present, and his widow, along with Duchamp scholar Paul B. Franklin, returned it to Yale in 2018. No word what or where the three others are, but Yale clearly has some idea.

a black painted apparatus on an x-shaped frame holds five glass plates along a spinning axle, with motor at the back. here the timelapse photo depicts the plates spinning so that the stripes painted on them create the optical illusion of concentric circles. the pompidou made this 1979 replica of duchamp's 1920 sculpture, rotary glass plates, under shady museum director pontus hulten, who stole sketches for it from yale university in 1960.
Marcel Duchamp? Rotative Plaques Verre, 1920/1979, a purchase by the Centre Pompidou

It turns out Hultén made another Rotative Plaques Verre, in French, for the Pompidou in 1979. In 1980 Hultén’s Pompidou published a facsimile set of 289 Duchamp notes and scraps with Paul Matisse, Duchamp’s step-son, with the originals in the collection. Nothing in there seems obviously stolen from Yale.

Marcel Duchamp’s Slightly Smaller Banner

Duchamp Large Glass Printed Banner at the Hirshhorn Museum. Technically, this is the back, but the view with people through it was nice, and the opposite view, with stanchions across a doorway during a preview, was not.

When Pontus Hulten , and then Richard Hamilton wanted to show Marcel Duchamp’s Large Glass but couldn’t, they made full-size replicas (actually Ulf Linde and Per Olof Ulfvedt made Hulten’s, based on photographs), which the artist eventually showed up and signed, “Certifié pour copie / conforme / Marcel Duchamp.”

And now those copies don’t travel, either. And there are other copies, but they’re non-conforme, I guess. So when the Hirshhorn Museum wanted to show the Large Glass in the context of related works from a large promised gift from Barbara and Aaron Levine, they faced a challenge.

Which was solved by an exhibition designer, who suggested printing a photo of the work at scale, and suspending it in the gallery. Acetate didn’t work. A free-floating polyester scrim didn’t work. But a scrim held taut with discrete cables and clamps worked just great. Evelyn Hankins, who curated the show, as well as the Hirshhorn’s recent Bob Irwin retrospective, which sent a giant, site-specific, taut scrim wall through the gallery, could only laugh.

Duchamp Large Glass banner detail, Hirshhorn Museum

I love it, so much that I want it. Unfortunately, the Association Marcel Duchamp does not want me to have it. Or anyone, for that matter. The Association, run by Duchamp’s (step-)grandchildren approved the Hirshhorn’s production of a banner (not a replica, and not, it turns out, full-size, but a couple of inches smaller) from the Philadelphia Museum’s (two-part, not entirely aligned) photodocumentation of the work, if they get it when the show’s over. The Hirshhorn, which will soon house one of the world’s major collections of minor Duchamps, prefers to be on good terms with the Duchamp estate rather than let me run out of the museum with the banner under my coat. Go figure.

STANCHION-FREE UPDATE: This looks very nice. esp. the opacity [image: thanks, mom]

Previously, related: After he interviewed Duchamp for the BBC Hamilton took home the full-scale transparency of the Large Glass they’d made. Later he not only made a replica of the Large Glass; he made a full-scale diagram edition of it, which is my favorite Large Glass replica of all. The Philadelphia Museum published a poster edition of it, and also, I just learned, a shower curtain, which is somehow a gift shop item but also in the collection. Putting the appropriate in appropriation since [checks notes to see when, exactly, the more uptight grandchildren took over the Association].

Paul Thek’s Tatlin’s Monument

paul_thek_tatlin_ica_phila_1977.jpg
Paul Thek’s birthday was last week, so I probably should have posted this photo of his re-creation of Tatlin’s Monument to the Third International then.
Thek installed this version of his Tower of Babel at his only US museum show in his lifetime, at the ICA Philadelphia in 1977. That’s Uncle Tom’s Cabin and a bathtub full of water inside it there.
Whatever points it loses for verisimilitude Thek’s Tatlin’s Monument makes up for being ahead of the game. The only widely known Tatlin replica at the time in the West was Pontus Hulten’s first version, built in 1968 for the Moderna Museet [where Thek had a show in 1971.] Hulten had made that one with T.M. Shapiro, Tatlin’s collaborator in the “Creative Collective.” Then in 1975, Shapiro went on to make another, more accurate version himself in Moscow, after gaining access to more original notes and documentation.
But then, I don’t get the sense that historical accuracy was ever Thek’s goal.

On The 2nd Through 8th Tatlin’s Monuments To The Third International

tatlin_tower_1920.jpgSo I’m slowly making my way through the 35-page press release [!! those were the days, right?] for MoMA’s 1968-9 exhibition, “The Machine As Seen At The End Of The Mechanical Age,” which included a long-lost, recently stumbled-upon in a Tempe, Arizona shed, Dymaxion Car, and curator Pontus Hulten’s freshly researched and replicated magnum opus, a life-size model of Vladimir Tatlin’s 1920 Monument To The Third International. Some choice excerpts on the remaking of:

Work was based on only four photographs (a crucial one was discovered during the process), a few drawings, some written descriptions and information from the sole living assistant of Tatlin. Troels Andersen, Ulf Linde and Per Olof Ultvedt of the Stockholm Academy of Art prepared a small wooden working model. From this, carpenters Arne Holm and Eskil Nandorf built the reconstruction, which is 15 feet 5 inches high, about the same size as Tatlin’s.
The research and reconstruction took about a year. The tower was first exhibited in the Tatlin show at Moderna Museet in Stockholm last summer. It was shipped to the United States in nine crates and reassembled by Mr. Nandorf in the Museum Garden.

So many interesting things here. Andersen had been working with T.M. Shapiro, part of a group called the “Creative Collective,” which included Tatlin, who made the first Monument in 1919-20, to document and resuscitate [to use Nathalie Leleu’s term] the neglected/suppressed history of the Russian Avant-Garde. In the catalogue, Hulten wrote, “For the first time, it seemed possible that an artist-engineer materializes the synthesis of architecture and sculpture.”
Leleu took a detailed look at contemporary curators’ use of refabrications and replicas; the excerpt dealing with reconstructions of Tatlin’s Monument was published in 2007 by Tate Papers.
She notes how Hulten was “a major protagonist in at least two of these reconstructions,” the first at Moderna Museet in 1968, and then at the Pompidou in 1979 for his historic show, Paris-Moscow. The Paris model was substantially different from the Stockholm model, Leleu writes, in part because Shapiro had recovered additional notes and rebuilt a Monument himself in 1975, but also because by 1979, Hulten was able to access original Tatlin materials in Russian museums and archives which had previously been blocked.
tatlin_models.jpg
In fact, because of last-minute denials of key loans by Soviet officials, Hulten’s show in 1968 consisted entirely of reconstructions, which led Hulten to dub his show “conceptual.” As it happens, this whole Tatlin saga and the fabrication of the Monument, was unfolding while the Moderna Museet was showing Andy Warhol’s work–including the Brillo Boxes, which would eventually become the subject of their own refabrication controversy.
It’s almost as if, while showing the dominant, if controversial, figure in American art, Hulten was simultaneously constructing an alternative to the arc of modernist and postwar art history. With an emphasis on the constructing, I guess.
Anyway, after an insurance dispute, the Parisian fabricators ended up making a new, Paris-style Monument for the Moderna Museet, and then consulting, along with Hulten, on the fabrication of additional Monuments in Moscow, one in London, and one in Los Angeles.
Maybe it’s clearer in her fuller paper, but in the Tate excerpt, Leleu refers to a “reconstruction project…in Washington,” which I think is actually the model built by USC Architecture School students for Maurice Tuchman’s LACMA 1980 exhibit, “The Avant-Garde in Russia,” which later traveled to the Hirshhorn.

Oh, The Places You Go, Little Brillo Box

Now that they’re selling for a million dollars or whatever, it’s hard to imagine how Warhol’s Brillo Box sculptures were perceived at the time they were made.
When they were lowly $300 sculptures, mechanically produced in seemingly endless supply, they were treated like furniture, traded and given away like party favors or the curatorial equivalent of hostess gifts. They were a medium of social, not economic currency. [At least not direct economic currency. Even from his early days as an illustrator, Warhol was already familiar with the art gift’s ingratiating self-promotion.]
boy's bedroom
The most common exhibition strategy for a Brillo Box was as a table. Two of the three Boxes I’ve seen in private collections were encased in Lucite and placed next to chairs. One had a lamp on it. The photo above [from janee’s flickr] shows what looks like a Stable Gallery box being used as a kid’s table in a San Francisco decorator showhouse. In 1988, Leo Castelli told New York Magazine he used two encased Brillo Boxes as side tables, but in 1965 when Factory photographer Bob Adelman snapped this picture at Castelli’s house, it was just the box and the phone. [See the full-size image at Corbis.]
irving_sandler_brillo.jpg

The Warhol Authentication Board’s report on the Pontus Hulten affair captures both the gift and furniture aspects of the dozen or so Boxes made in 1968:

Of the six Stockholm type boxes known to exist, three were given to [curator and later museum director Ollie] Granath as “souvenirs” for having helped Hulten with the Moderna Museet exhibition. Hulten kept the other three for his own use; two served as bedside tables for his children. [pp.9-10]

Of the three that Hulten kept, one was later given to the silkscreener who made the Malmo type boxes. [p. 10]

[Hmm, I wonder if Castelli’s 1988 sale of his end table “to European collector” for $50,000 motivated Hulten to trade one of his own Stockholm type table/”souvenirs” in order to, uh, complete his edition?]
oberlin_brillo_boxes.jpgThe report also mentions the 100 Pasadena type boxes, plus “as many as 16” additional Boxes identified in the CR that were “given as gifts or sold.” Two of those 16 are the Oberlin Brillo Boxes, [right] which Warhol gave to Pasadena Art Museum curator John Coplans, who later donated them to the college’s Allen Museum.
All this gifty goodness and casual domestic use leads me to speculate that LACMA’s “missing” Kellogg’s Corn Flakes boxes–10 known, plus at least 33 and maybe more, if they produced as many as Pasadena did–were treated as thank-you gifts to donors who paid for their fabrication, or were sold to “friends and family” of the museum. So keep your eye out.

Facture-Checking Warhol’s Brillo Boxes

warhol_brillo_christies_98.jpg
The Brillo Box formerly known as Stockholm type, and formerly known as being by Andy Warhol, sold at Christie’s in 1998.
So awesome. The Beverly Hills art dealer Robert Shapazian’s bequest to the Huntingon Museum of 10 Brillo Boxes by Andy Warhol has brought the whole tangled Brillo Box versioning and authenticity debate back into the news. As the LA Times’ Christopher Knight reports, Shapazian’s Brillo Boxes include one 1964 Stable Gallery box–and nine Pontus Hulten Boxes, made by the legendary founding director of the Moderna Museet. And the Pompidou. And MoCA.
Until this summer, those nine would have been called Stockholm Type. But following the completion of the Warhol Authentication Board’s 2+year investigation and the release of their 27-page report [Jul 19, 2010 pdf via LA Times], the 105-120 or so Stockholm Types have been split into Stockholm Types and Malmo Types.
Hulten had somewhere between 10 and 12, but not more than 15, boxes made after his 1968 Warhol exhibition at the Moderna Museet closed. He did this, he said, because Warhol told him to “make them over there.” Hulten apparently pocketed that date and authorization. When, in 1990, he had 105 Boxes fabricated in Malmo for a series of exhibitions, he referred to an “old authorization.” The only thing missing, it seems, was documentary evidence of this readymaking on Warhol’s side.
There was extensive context provided to show that fabricating works was part of Hulten’s standard practice–he had replica Tatlins and replica Duchamps made, including, even, a Large Glass, which Duchamp later signed [as a “copie conforme”]. Hulten’s texts and statements show he considered Duchamp and Warhol as readymade brothers.

Following the logic of Duchamp and taking it to another power, Hulten interpreted Warhol’s 1964 Stable Gallery box sculptures not as factured works of art, but as repeatable, ready-made objects, that were interchangeable with real Brillo Soap Pads cartons or replicas.

And then the Board does what authentication boards do: it examines the physical details of each type of box, distinguishing Warhols based on the traditional notion of the character of their painted surface, or facture. Stockholm types were “painted and sanded multiple times to achieve a high degree of finish before they were printed,” but Malmo types “appear to have been painted with a roller.” Stockholm types have mitered corners, but Malmo types [and Stable Gallery types, for that matter] have abutted joints. Malmo types are made with a nail gun, Stockholm types were nailed by hand. And so on.
The conceptual difference between these two approaches to Warhol’s work is fascinating, and Hulten clearly felt justified and correct in the way he had his Brillo Boxes made. The fact that Hulten’s 1968 boxes were made in 1990 seems to have been more broadly known and accepted within the Scandinavian museum and art community. But he also did not have any problem “misrepresent[ing] the works and falsif[ying] their history” to the Estate, the Board, and the Catalogue Raisonne.
And so, the Board has reclassified all Hulten boxes as “exhibition related copies” [Stockholm] and “exhibition copies” [Malmo]. Any questions?

The International Symposium for Andy Warhol’s Brillo Boxes

bidlo_not_warhol_1991.jpg
The Moment has a Q&A with Mike Bidlo
, whose work, Not Warhol (Brillo Boxes, 1964), 2005 is currently on view in the Lever House lobby:

Did you ever meet him [Warhol] more formally?
Yes, at a party at Jean-Michel Basquiat’s loft. There was a big group of people there, but I knew he knew who I was. It was a little awkward.
What about Gerard Malanga?
I was with him on a Brillo Box symposium in Nuremberg, Germany [in 1999] with Arthur Danto and others. He might come to the opening. To me he’s the expert.

Malanga is the expert because he, along with Billy Name, did much of the fabrication of those first Stable Gallery Brillo Boxes in 1964. But everyone knows that story. What I want to know about is this “Brillo Box Symposium.”
According to a footnote at warholstars.org, The International Symposium for Andy Warhol’s Brillo Boxes was held “under the auspices of the Akademie der Bildenden Kunste in Nuernberg, Friday, 19 November 1999.” Danto presumably discussed his 1998 paper, “The End of Art,” which took Brillo Boxes as the inflection point of a 3,000-year art historical cycle or something.
Malanga’s paper titled, “How we made the Brillo Boxes,” was reprinted in his 2002 book, Archiving Warhol. It provides the most familiar accounts of Malanga, Billy Name, and Warhol painting, turning, screening, and turning all seven varieties of the box sculptures in the first couple of months of 1964. [Four Stable Gallery boxes sold at Christie’s in 2006 for $973,000.]
warhol_boxes_64_christies.jpg
But the 1964 Brillo Boxes aren’t the only ones Warhol made. Or Bidlo. Or–well, hold on. Back to The Moment:

If your Brillo Boxes shouldn’t be considered a simple substitute for the originals, what should New Yorkers be looking for?
There are so many more layers. When you start peeling back the layers you see that Warhol did all these different versions himself. There’s the Stockholm version, there’s the Pasadena, the original Stable gallery version. So really it’s about learning about the different providences [provenances? -ed.] of the piece, the situations that they were made for.

The image above is from the Tate Magazine, of Not Warhol (Brillo Boxes, 1969), 1991, and is Bidlo’s replica of the 100 boxes Warhol authorized the Pasadena Museum to fabricate in 1969-70 [LACMA was allowed to refabricate 100 Kellogg’s boxes. Warhol donated both sets of boxes to the respective museums.]
And before that, there were the 100 boxes Warhol authorized Pontus Hulten and the Moderna Museet to make in Sweden for the 1968 show organized by Kasper Koenig. Or was it 500? Or was that 500 actual cardboard Brillo Boxes bought from the company and 100 wooden ones to fill in? Or 10?
Until 2007, everyone thought they kind of knew. Or they didn’t think much about it. Then some Swedish investigative journalists from Expressen reported that no wooden boxes were ever exhibited in 1968, only cardboard.
And the 94 1968 “Stockholm Type” Brillo Boxes which passed the Warhol Authentication Board’s test, and were accepted into the 2004 catalogue raisonne, were actually part of a batch of 105 boxes Hulten fabricated in 1990, three years after the artist’s death, in Malmo, Sweden. And that Hulten represented them as 1968 works in shows in St Petersburg and Copenhagen that year. And that he sold at least 40 of them in 1994 as 1968 works. [Does that include this group of 10?] And that he gave six of them to the Moderna Museet in 1995 as 1968 works.
warhol_brillo_christies_98.jpg
Yow. “Provenance: Acquired directly from the artist by Pontus Hulten, Stockholm” – Christie’s, 1998.
The Authentication Board hastily examined the Stockholm Type boxes and issued a letter to owners, saying there were two types of Stockholm Box, one of which might actually have been made in 1968 or so. Maybe there are 10 of those. But there are no documents so far authorizing either those 10, or the 105 Hulten made, only the Stable Gallery and the Pasadena boxes, that’s it. So far. And yet they fully accepted the Stockholm Boxes, no sweat. At this point, the only thing the Warhol Foundation people are saying is that they had nothing to do with this mess.
But what in the world was Pontus Hulten thinking? I mean, come on, the guy’s a modern art museum demigod who founded the Moderna Museet, the Pompidou, and MoCA. It’s not like he really could have just thought, “What the hell, I’ll order me up 100 Brillo Boxes and start showing, selling, and donating them as if they’re from 1968.” Could he?
Did Hulten get authorization from Warhol in 1968, then not really use it [all], and just assume it was still valid? ArtNews quotes an unidentified source as saying that Hulten fabricated his 1990 boxes at the Malmo Konsthall with the help of its director [and Hulten’s friend] Björn Springfeldt. Surely he could characterize how he and Hulten talked about the motives and assumptions for the production. [Factcheck: ArtNews says Springfeldt was director of Malmo Konsthall in 1990 when these boxes were fabricated. Actually, he had quit in 1989, to become director of Moderna Museet. He succeeded Olle Granath, who had succeeded Hulten, and who had been a co-curator of the Warhol show, and who was directly involved in its installation. He also owns three Stockholm Style Brillo Boxes he says were made in 1968. If there’s anyone in the Swedish museum world not directly implicated in this story, would you please raise your hand?]
How different is Hulten’s situation from, say, Giuseppe Panza’s later controversies over authorization and remote fabrication of work by artists like Judd, Flavin, Andre, and Nauman? Does this Brillo Boxes question dovetail with the emergence of artists’ certificates and minimalist-style, no-artist’s-touch production? Are there other examples lurking out there where artists phoned a piece in, then didn’t actually get involved–or even see–the final product? I’m going to guess yes.
If ever there were a time for another Brillo Box Symposium, it’s right now.

Pour Copie Conforme

After bagging on Blake Gopnik’s comments on Marcel Duchamp playing the buyers of his readymades for fools, I started looking more closely at Duchamp’s actual statements and working process. It’s so easy to consider him as just a source of ideas, and to forget that in fact, he expended a great deal of effort and time on the creation of objects.
On the other hand, that dude would sign just about anything that wasn’t nailed down. Including readymades that were really made, or found, or bought, by others. All over the place. The only thing that stopped him, it seems, was Arturo Schwartz, who insisted Duchamp stop signing stuff to protect the value of the 1964 readymade editions.
duchamp_hopper_hotel_green.jpg
One example: when the late photographer, painter, and avant garde filmmaker Dennis Hopper met Duchamp on the day of the opening of his 1963 retrospective in Pasadena, he grabbed a sign from the Hotel Green, where Duchamp was staying, and asked him to sign it. And he totally did.
Another, from Francis Naumann’s incredible practice history, Marcel Duchamp: The Art of Making Art In The Age Of Mechanical Reproduction, which I picked up at the suggestion of John Powers [Naumann’s gallery was the site of that fantastic Duchamp chess show last year.]:

During the time of the Pasadena exhibition, Duchamp was invited to attend a breakfast in his honor at the home of Betty Asher, an important collector of contemporary art who lived in West Los Angeles. Among the thirty or more guests she invited, one of them, Irving Blum, then owner of the Ferus Gallery in Los Angeles, asked Duchamp if he would consider signing a bottle rack he had found and purchased from a local thrift shop. Just in case the artist agreed, Blum brought the item along with him to the breakfast. When Blum asked, Duchamp responded: “Gladly,” whereupon Blum retrieved the work from the trunk of his car and Duchamp signed it on the bottom rung, adding the usual inscription, “pour copie conforme,” and the date: “1963-14”. When Blum was in the process of returning this treasured artifact to the trunk of his car, Richard Hamilton reportedly rushed out of the Asher house and quipped: “You are, of course, aware of the fact, Mr. Blum, that in order to devalue his work, Duchamp signs everything.” [p.235, emphasis added for the awesome parts]

Indeed, and one of the last things he signed was the replica of Bicycle Wheel which Hamilton had made, and had asked Duchamp to sign the next time he passed through London. [Blum donated his Bottle Rack, below, to the Norton Simon Museum in 1968 after Duchamp’s death.]
duchamp_bottle_rack_blum.jpg
And Pontus Hulten told how Duchamp said the Modernamuseet could save money by making a bunch of readymade replicas for a show instead of shipping them: “Duchamp later signed everything. He loved the idea that an artwork could be repeated. He hated ‘original’ artworks with prices to match.” [p.213]
Which is making me nod and laugh out loud right now as I sit here, with a pile of pens, signing my name over and over and over on the stack of certificates for the edition I’m doing with 20×200.com, which is going to be announced very soon. Stay tuned.
