Issued by Germany (Deutsche Bundespost) in 1973, this 30 Pfennig stamp commemorates the 15th German Protestant Church Congress (Kirchentag) held in Düsseldorf. The minimalist design features a stylized human profile and symbolic cross elements, reflecting spiritual reflection and dialogue. The inscription “Nicht vom Brot allein” (“Not by bread alone”) highlights the event’s theme of faith and moral values beyond material needs. The modern graphic style makes this issue visually distinctive among 1970s German commemoratives. It is an appealing thematic piece for collectors of religion, church events, and German cultural history.
