Issued in 1944 by Germany (Grossdeutsches Reich), this 6+24 Pfennig semi-postal stamp commemorates Tag der Briefmarke (Stamp Day). The design features a stylized post horn and envelope, symbolizing communication and the philatelic tradition. The “+24” indicates a postal tax surcharge, commonly used for charitable or cultural funding during the era. Its deep green monochrome engraving gives it a bold wartime aesthetic. A historically significant issue from the final years of the Third Reich, it remains a notable piece for WWII-era and Stamp Day thematic collectors.
