This 18¢ definitive stamp from the United States features a portrait of George Washington, the nation’s first President, alongside the Washington Monument. Issued in 1981 for presorted first-class bulk mail, it forms part of the Americana series. The design, with its clean typography and patriotic color scheme, emphasizes efficiency in postal service and celebrates national heritage. The “PRESORTED FIRST-CLASS” overprint designates its intended use for business and organizational mailings rather than individual correspondence.
