Nude Descending a Staircase, No. 2 is a 1912 painting by Marcel Duchamp. The work is widely regarded as a Modernist classic and has become one of the most famous of its time. Before its first presentation at the 1912 Salon des Indépendants in Paris it was rejected by the Cubists as being too Futurist. It was then exhibited with the Cubists at Galeries Dalmau's Exposició d'Art Cubista, in Barcelona, 20 April – 10 May 1912. The painting was subsequently shown, and ridiculed, at the 1913 Armory Show in New York City. Marcel Duchamp, 1912 — painted at 25. Canvas and oil paint. 147 × 89.2 cm.
