Marcel Duchamp’s window display (the mannequin is his & #39;Lazy Existence& #39;) at the Gotham Book Mart, NYC for André Breton’s & #39;Arcane 17& #39; in 1944. Maya Deren took the photograph, capturing Breton himself reflected in the window.
Modernist artists and NYC window dressing seems to have been quite a thing. Here& #39;s Robert Rauschenberg and Jasper Johns& #39; window for Bonwit Teller, 1950 (the Duchamp piece in the previous tweet is of course & #39;Lazy Hardware& #39;, the lazy existence is entirely mine).
