This 40 Pfennig commemorative stamp from Germany (Deutsche Bundespost) was issued in 1973 to honor Otto Wels (1873–1939), the notable German Social Democratic leader remembered for his courageous stand against the Enabling Act in 1933. The design features a bold monochrome portrait in deep burgundy against a soft lilac background, characteristic of the 1970s German commemorative portrait style. A clean vertical inscription “DEUTSCHE BUNDESPOST” appears at left, with Wels’ name and birthdate along the right border. A desirable issue for collectors of German political history, prominent figures, or 1970s Bundespost commemoratives.
