This Austrian 3 schilling stamp, issued in 1981, honors Hans Kelsen (1881–1973), a prominent legal scholar and principal architect of Austria’s 1920 Federal Constitution. The deep red design features a finely detailed portrait of Kelsen, wearing glasses, with inscriptions marking his role in shaping the constitution (“Mitgestalter der Bundesverfassung”). Designed by A. Pilch and engraved by A. Nefe, it reflects Austria’s tradition of honoring intellectual figures who shaped the nation’s democratic framework.
