This Austrian 3 Schilling stamp, issued in 1981, commemorates the 7. Internationale Katholische Arbeitnehmertagung (7th International Catholic Workers’ Meeting). The design by F. Dorner and K. Leitgeb depicts two muscular workers breaking stones, symbolizing labor, unity, and solidarity. Above them is the emblem of the Katholische Arbeiterbewegung (KAB – Catholic Workers’ Movement). Rendered in blue and black tones, the stamp reflects the social and faith-based commitment to workers’ rights and dignity. A notable issue for collectors interested in labor history, religion, and Austrian commemoratives.
