That's not art!
Theodore Roosevelt (1858-1919), 26th US President commenting on the artwork at the Armory Show of 1913
The legendary International Exhibition of Modern Art, also known as The Armory Show of 1913, introduced United States art patrons to Modern Art. From February 17 - March 15, the 69th Regiment Armory in New York featured 1250 avant-garde artworks, representing over 300 European and American artists.
The goal of the exhibition was to question the boundaries of art as an institution. Critics and news sources of the day viewed the pieces as nothing less than scandalous. Perhaps the single most controversial piece was Marcel Duchamp's Nude descending a staircase, No 2, which one New York Times' art critic termed -- an explosion in a shingle factory.
