This classic 1-cent United States stamp features engraved portraits of George Washington and General Nathanael Greene, two essential leaders of the American Revolutionary War. Issued in 1937, it forms part of the Presidential and historical definitive issues of the era. Between the two portraits is a fine engraving of Mount Vernon, Washington’s iconic Virginia estate, rendered in rich green ink. The strong historical theme, attractive symmetrical layout, and crisp line engraving make this a popular item among collectors of early 20th-century U.S. philately and Revolutionary-era subjects.
