This United States postal stationery envelope features the 6¢ “Paul Revere – Patriot” indicium, depicting the famous American patriot associated with the midnight ride during the American Revolution. The brown printed design shows a stylized colonial portrait and the inscription “Paul Revere – Patriot,” typical of U.S. postal envelopes issued during the late 1960s period. Affixed beside the indicium is a 2¢ stamp honoring Frank Lloyd Wright, the influential American architect known for iconic buildings such as Fallingwater and the Guggenheim Museum. Issued in 1966, the stamp commemorates Wright’s contributions to modern architecture. The combination creates a mixed-franking postal stationery item, where additional adhesive postage was added to supplement the pre-printed envelope value. Such pieces are interesting to collectors studying U.S. postal stationery usage and commemorative stamp combinations.
