Issued by Germany (Berlin) in 1971, this commemorative set celebrates the 50th anniversary of the AVUS (Automobil-Verkehrs- und Übungsstraße) motor racing circuit, established in 1921. The 30 Pfennig stamp depicts an early vintage racing car with the iconic Berlin radio tower in the background, symbolizing the circuit’s historic roots. The 60 Pfennig stamp features streamlined mid-20th-century racing cars speeding along the famous steeply banked curve. A dynamic tribute to Germany’s motorsport heritage, this set is highly attractive for thematic collectors of racing, transport, and automotive history.
