This 20 Pfennig commemorative stamp from West Germany honors Heinrich von Stephan (1831–1897), founder of the Universal Postal Union (UPU) and one of the most influential postal reformers in history. Issued by Deutsche Bundespost, the design features a bold numeral “20” set against finely engraved wavy red lines, overlaid with Stephan’s facsimile signature. Vertical inscriptions celebrate his role as “Begründer des Weltpostvereins” (Founder of the World Postal Union). Sharp typography and balanced composition make this a classic early-Federal-Republic engraving and a desirable issue for postal-history collectors.
