This German 24 Pfennig stamp honors Heinrich von Stephan (1831–1897), the influential postal reformer and founder of the Universal Postal Union (UPU). Issued by the post-war Deutsche Post, it features a finely engraved profile portrait in a rich reddish-brown tone, reflecting early reconstruction-era printing styles of the Allied Occupation period. The issue commemorates the 50th anniversary of Stephan’s death, highlighting his essential contributions in modernizing Germany’s postal service. A staple of mid-20th-century German philately, it remains a valued piece for collectors specializing in postal history, UPU themes, and post-WWII issues.
