Issued by Germany during World War II under the name Grossdeutsches Reich, this 15 + 10 Pfennig semi-postal stamp features a detailed depiction of a German Sturmgeschütz III (StuG III) assault gun advancing through the field, symbolizing armored strength on the Eastern Front. The additional +10 Pfennig surtax supported wartime welfare efforts. Printed in a deep carmine shade, it forms part of the 1943 “War Winter Relief” (Winterhilfswerk) series highlighting German military equipment. A striking militaria-themed issue sought after by collectors of wartime philately and historical propaganda designs.
