Issued by East Germany (DDR), this 25 Pfennig stamp highlights the Gesellschaft für Sport und Technik (Society for Sport and Technology). The design features a stylized figure at a control panel, symbolizing radio operation, technology training, and youth technical education. The organization played a significant role in preparing young people for scientific, technical, and military fields in the GDR. The modernist artwork, with geometric forms in blue, pink, and white, reflects the DDR’s emphasis on progress and technical skill development during the late 1960s.
