Issued by Germany (Berlin) in 1967, this 30 Pfennig commemorative stamp celebrates the 25th Great German Radio Exhibition (Große Deutsche Funkausstellung) held in Berlin from 25 August to 3 September 1967. The design prominently features the iconic Berlin Radio Tower (Funkturm), a symbol of broadcasting and technological progress. Behind the tower appears a stylized television screen with colorful mosaic patterns and a waveform representing radio and television signals. The stamp reflects the rapid development of broadcasting technology during the 1960s and Berlin’s importance as a center for electronics and communication exhibitions.
