This 20 Pfennig commemorative stamp was issued by Deutsche Bundespost in 1968 to mark the 82nd Deutscher Katholikentag (German Catholic Day) held in Essen.
The design is symbolic and modernist: a yellow cross at the center represents faith, while a white dove symbolizes peace and the Holy Spirit. Surrounding atomic orbits evoke the contemporary theme “Mitten in dieser Welt” (“In the midst of this world”), emphasizing the Church’s engagement with science, society, and modern life.
A striking example of 1960s West German graphic design, it reflects the post-Vatican II spirit of reconciling faith and modernity.
