Duchamp or Rrose Sélavy) Leather valise containing miniature replicas, photographs, color reproductions of works by Duchamp, and one “original" drawing [Large Glass, collotype on celluloid, 7 1/2 x 9 1/2" 1935-41 Between 1935 and 1940, Marcel Duchamp created a deluxe edition of twenty boxes, each in a brown leather carrying case but with slight variations in design and content. A later edition consisting of six different series was created during the 1950s and 1960s; these eliminated the suitcase, used different colored fabrics for the cover, and altered the number of items inside. Each box unfolds to reveal pull-out standing frames displaying Nude Descending a Staircase and other works, diminutive Readymades hung in a vertical "gallery," and loose prints mounted on paper. Duchamp included in each deluxe box one "original."
