This rare 1966 silkscreen poster commemorates the "Hommage à Caissa" exhibition at New York’s Cordier & Ekstrom Gallery, a fundraiser organized by Marcel Duchamp for the American Chess Foundation. The event featured contributions from 36 iconic artists, including Salvador Dalí, Jasper Johns, and Alexander Calder, and is famously remembered for Andy Warhol’s uninvited "guerrilla attack" appearance with the Velvet Underground. The poster's design incorporates RSVP cards sent to participating artists, some featuring personal notes and autographs.
