Issued by the Republic of Austria in 1980, this 2-Schilling commemorative stamp honors the 750th anniversary of the Diocese of Graz-Seckau, one of the country’s most historic ecclesiastical institutions. The design, by A. Pilch and engraved by K. Leitgeb, features a sculptural image of a medieval bishop holding a crozier and book — symbolizing spiritual authority and learning. Rendered in a dignified bluish-gray tone, the artwork evokes Romanesque stone carvings typical of Austrian sacred architecture. The inscription “750 Jahre Diözese Graz-Seckau” celebrates the long continuity of Christian tradition in Styria.
