High Quality Content by WIKIPEDIA articles! Many exhibitions have been held in the vast spaces of U.S. National Guard armories, but the Armory Show refers to the 1913 International Exhibition of Modern Art that was organized by the Association of American Painters and Sculptors. The exhibition ran in New York City`s 69th Regiment Armory, on Lexington Avenue between 25th and 26th Streets, from February 17 until March 15, and became an important event in the history of American art, introducing astonished New Yorkers, accustomed to realistic art, to modern art. The show served as a catalyst for American artists, who became more independent and created their own "artistic language".
