Cubism and modern European art was introduced into the United States at the now legendary 1913 Armory Show in New York City, which then traveled to Chicago and Boston. In the Armory show Pablo Picasso exhibited La Femme au pot de moutarde (1910), the sculpture Head of a Woman (Fernande) (1909–10), Les Arbres (1907) amongst other cubist works. Jacques Villon exhibited seven important and large drypoints, his brother Marcel Duchamp shocked the American public with his painting Nude Descending a Staircase, No. 2 (1912). Francis Picabia exhibited his abstractions La Danse à la source and La Procession, Seville (both of 1912). Albert Gleizes exhibited La Femme aux phlox (1910) and L'Homme au balcon (1912), two highly stylized and faceted cubist works. Georges Braque, Fernand Léger, Raymond Duchamp-Villon, Roger de La Fresnaye and Alexander Archipenko also contributed examples of their cubist works.
