Winslow Homer was an American landscape painter and printmaker, best known for his marine subjects. He is considered one of the foremost painters in 19th-century America and a preeminent figure in American art.
Largely self-taught, Homer began his career working as a commercial illustrator. He subsequently took up oil painting and produced major studio works characterized by the weight and density he exploited from the medium. He also worked extensively in watercolor, creating a fluid and prolificoeuvre, primarily chronicling his working vacations
In 1962, the U.S. Post Office released a commemorative stamp honoring Winslow Homer. Homer's famous oil painting "Breezing Up", now hanging in the National Gallery in Washington DC, was chosen as the image for the design of this issue. On August 12, 2010, The Postal Service issued a 44-cent commemorative stamp featuring Homer's "Boys in a Pasture" at the APS Stamp Show in Richmond, Virginia. This stamp was the ninth to be issued in a series entitled "American Treasures". The original painting is part of the Hayden Collection at the Museum of Fine Arts in Boston.
