You cannot fully understand Twombly’s art unless you know that there is gators.
Twombly went to Rauschenberg’s house in Captiva in November 1970 and made collages; in December 1971 and made prints, but those catalogues raisonnés were checked out, so who knows? In the winter of 1972, he made this collage as a Christmas present for Rauschenberg. It has four, possibly five, postcards of alligators on it.
I really didn’t think of collage as a Twombly thing. But it looks like a major part, maybe even most of his works on paper in the 1970s were collages. He collaged with catholic zeal: Leonardo images; mushrooms and natural history book illustrations; graph and drawing paper; fragments of other drawings; and, in Captiva, especially, touristy postcards.
Twombly’s lines here index the placement and width of the postcards, and of their crossed out captions, as if the composition is a conceptual schematic of itself. It’s still very much a drawing.
