Issued by Austria in 1969, this 1.80 schilling stamp features a stunning depiction of Duke Leopold V from the medieval stained-glass window of Klosterneuburg Monastery. The artwork, by A. Pilch and A. Fischer, captures Leopold V holding the red-white-red Austrian shield—an emblem closely tied to the nation’s heraldic origins. Part of the “Gothic Windows” definitive series, the stamp celebrates Austria’s rich artistic and dynastic heritage through meticulous color and design inspired by 12th-century craftsmanship.
