A catalog documenting an exhibition of Marcel Duchamp’s editioned readymades at Gagosian Gallery, New York, replicating his American debut at Cordier & Ekstrom in the same building in 1965 and including new essays. Marcel Duchamp’s first readymade, a standard bicycle wheel attached to a wooden stool, came about “as a pleasure, something to have in my room the way you have a fire, or a pencil sharpener, except that there was no usefulness.” Over the ensuing decades many of his readymades were lost or destroyed, but in 1964 Duchamp, working with acclaimed gallerist Arturo Schwarz, supplanted the original readymades with fourteen precisely executed editioned multiples, a process which culminated in an exhibition in New York in 1965.
