This German 75 Pfennig commemorative stamp honors Heinrich von Stephan (1831–1897), the visionary postal reformer credited with shaping the modern German postal system and helping found the Universal Postal Union. Issued by Deutsche Post in the immediate post-war period, the design features a finely engraved profile portrait in deep blue, reflecting the classical aesthetic of early German reissues under Allied occupation. Collectors value this stamp for its historical significance, clean typographic layout, and its connection to early postal reconstruction in post-WWII Germany. A key piece for thematic collections on postal history and UPU pioneers.
