Issued in 1980 by Austria, this 4 schilling commemorative stamp celebrates the 500th anniversary of Baden bei Wien receiving city rights in 1480. The central design features the historic city coat of arms from 1566, illustrating two figures bathing in wooden tubs—a nod to Baden’s famed thermal springs. Framed in a decorative purple border, the stamp highlights both civic pride and the spa town’s cultural heritage. Designed by Otto Zeiller and engraved by Wolfgang Seidel, it's a striking example of heraldic philately.
