Issued to mark the 150th anniversary of the Siege of Yorktown (1781–1931), this classic U.S. commemorative honors the allied leaders who secured American independence. The stamp features finely engraved oval portraits of Rochambeau, George Washington, and Admiral de Grasse, framed in a bold red and black design typical of early 20th-century U.S. issues. Its historical theme and strong bi-color typography make it a standout piece for Revolution or military-history collections. Popular with both topical and classic U.S. collectors, it remains a staple album space-filler and exhibition item. A timeless engraved commemorative from the golden era of American stamp design.
