Issued in 1948 during the Allied Occupation period, this stamp honors Heinrich von Stephan, the founder and organizer of the modern German postal system and a pioneer of international postal cooperation. The engraved portrait design reflects classic post-war German philatelic style, emphasizing national reconstruction through communication services. Stephan played a major role in establishing the Universal Postal Union, making this issue historically significant for postal history collectors. The deep blue 75 Pfennig denomination was commonly used for higher postal rates of the period. A key thematic addition for collectors specializing in postal pioneers, communications, or post-war Germany.
