It was dedicated yesterday in Richmond, Va., during the American Philatelic Society StampShow 2010.
The stamp, the latest in the U.S. Postal Service's American Treasures series, features Winslow Homer's 1874 painting "Boys in a Pasture," on display at Boston's Museum of Fine Arts.
Homer's work largely focuses on landscapes and scenes of American life.
It's Homer's third time on a U.S. postage stamp. The first was in 1962, featuring "Breezing Up (A Fair Wind)," a painting of a man and three boys sailing. In 1998 a stamp carried his painting "The Fog Warning."
