Issued by Deutsche Bundespost Berlin in 1967, this 30-Pfennig commemorative stamp celebrates the 25th Große Deutsche Funk-Ausstellung, one of Germany’s major radio and broadcasting exhibitions. The design features the iconic Funkturm Berlin (Berlin Radio Tower) set against a vibrant mosaic of color blocks symbolizing modern broadcasting and transmission. A stylized white frequency wave overlays the background, emphasizing the theme of communications technology. This issue is popular among collectors of Berlin commemoratives, technology-themed philately, and 1960s European exhibitions.
