I looked at a lot of Robert Watts while researching and writing about his friend Aaron Kuriloff. I really liked it. MoMA has some very nice and interesting chrome Watts pieces on view right now in the 1960s hang of the permanent collection galleries, but I have never seen this in person. Pearl Necklace is a 1:1-scale photo mounted on wood. The wire makes me think it had to have been designed for wearing, which is awesome. In 1967 Kuriloff had his last show, of 1:1-scale photos of office furniture and equipment he called "photo-factuals." He'd been making them for a couple of years, and I'm pretty sure he and Watts were up on/involved in each other's work. I, for one, would like to know and see more.
