Issued by Austria in 1976, this commemorative 3 schilling stamp honors the 1000th anniversary of the founding of the Duchy of Carinthia (976–1976). The central image shows the Herzogstuhl (Duke's Chair) on the Zollfeld plain—a symbol of medieval Carinthian ducal authority. The stamp's bold orange background highlights this ancient coronation seat, steeped in early European feudal tradition. Designed by A. Exax and engraved by W. Pfeiler, it reflects both historical reverence and national pride.
