The 1913 Armory Show contained approximately 1300 works by 300 artists. Many of the original works have been lost and some of the artists have been forgotten. The list of artists in the Armory Show, while not complete, includes nearly all the artists from the United States and Europe who were exhibited in the Armory Show of 1913. The list is largely drawn from the catalog of the 1963 exhibition, 1913 Armory Show 50th Anniversary Exhibition, organized by the Munson-Williams-Proctor Arts Institute. Many exhibitions have been held in the vast spaces of U.S. National Guard armories, but the Armory Show refers to the International Exhibition of Modern Art that was organized by the Association of American Painters and Sculptors and opened in New York City's 69th Regiment Armory, on Lexington Ave
