Do you still use stamps? If yes, next time you’re at the post office, get a sheet of the new Modern Art in America series featuring iconic American works by Stuart Davis, Charles Demuth, Aaron Douglas, Arthur Dove, Marcel Duchamp, Marsden Hartley, Georgia O’Keeffe, John Marin, Gerald Murphy, Man Ray, Charles Sheefer, and Joseph Stella. The series marks the 100th anniversary of the opening of the landmark Armory Show held in New York.

At the bottom of the sheet is a 1915 quote from Marcel Duchamp: America is the country of the art of the future. Almost 100 years later, looks like he was right.

Your letters will look that much cooler with Charles Demuth’s I Saw the Figure 5 in Gold on the envelope.
