This 20+10 pfennig semi-postal stamp was issued by the German Democratic Republic (DDR) in 1964 to honor Heinz Steyer (1909–1944), a German resistance fighter executed during World War II. The portrait is finely engraved against a soft rose background, with his name and life years inscribed along the sides. The surtax (+10) supported cultural and social causes within East Germany. Steyer, a member of the German Communist resistance, became a symbol of anti-fascist courage, and his memory was commemorated through philately and memorials in the DDR. This stamp forms part of the series celebrating resistance heroes and holds historical significance for collectors of DDR history, political themes, and wartime commemoratives.
