This Austrian 3 schilling commemorative stamp was issued in 1976 to mark the 1000th anniversary of the Duchy of Carinthia (Kärnten), one of Austria’s historic regions. The design by W. Pfeiler features the Herzogstuhl (Duke’s Chair) on the Zollfeld plain, a stone throne used in medieval times for the ceremonial installation of Carinthian dukes. The bold orange background highlights the stone monument, symbolizing endurance and historical continuity. Engraved by A. Exax, the stamp celebrates Carinthia’s deep cultural and political roots within the Austrian heritage.
