In 1916, Marcel Duchamp recreated his Nude Descending a Staircase (No. 2) for his patrons Louise and Walter Arensberg, who had coveted the notorious painting since seeing it at the Armory Show in New York three years earlier. Given that the original was now owned by a San Francisco art dealer who did not want to part with it, Duchamp had a commercial photography studio enlarge a postcard image of the work to match the proportions of the original canvas. The colossal photograph was then meticulously retouched by the artist in a wide variety of mediums, including pencil, ink, watercolor, and pastel, to replicate the crisply delineated forms of the original composition.
