Poster for the German Grand Prix (for race cars: "fur Rennwagen") at Nurburgring on 15 July 1934. Rudolf Caracciola did not compete in this race, as he was out for all of 1933 due to an accident in practice ["training"] at Monte-Carlo, and did not return to racing until August 1934. The car depicted in the poster appears to be a M-B W25, displaying the flags of the European nations. The W25 was built for the new 750-kg [maximum weight] Formula that began in 1934.
