The influential works of 12 American modern artists were honored today by the United States Postal Service and the Armory Show with the dedication of the Modern Art in America, 1913-1931 stamps. The ceremony took place 100 years after the first Armory Show, a groundbreaking international exhibition which offered many a first look at modern art.

Richard Uluski, U.S. Postal Service vice president, Northeast Area Operations, was joined in the ceremony by Noah Horowitz, managing director, The Armory Show; Valerie Paley, vice president, Scholarly Programs and New York Historical Society and honored guest, Dorothy Vogel, The Vogel Collection.
