The Armory Show, officially titled 'The International Exhibition of Modern Art', contained some 1250 paintings, sculptures, and decorative works by over 300 avant-garde European and American artists.
The purchase of Cézanne's 'Hill of the Poor' by the Metropolitan Museum of Art signaled an integration of modernism into New York's Establishment museum, but among the younger artists represented, Cezanne was already an established master.
Among the scandalously radical works of art, pride of place must go to Marcel Duchamp's Cubist "Nude Descending a Staircase," painted the year before, in which motion was expressed by successive superimposed images, as in motion pictures. The work was originally slated to appear in Paris titled "The Bride stripped bare by her bachelors, even", but the Salon Cubists demanded that Duchamp retitle it to avoid possible scandal. Instead, Duchamp removed the work from the exhibition entirely, and it went on to create a scandal at the Armory Show instead.
Duchamps' brother, who went by the nom de guerre Jacques Villon, also exhibited, sold all his Cubist painting,s and struck a sympathetic nerve with New York collectors, who supported him for the next decades.
