In 2009, the Prototyp car museum in Hamburg, Germany, organized a special two-month exhibit where 25 classic, streamlined automobiles had an unprecedented "aerodynamic rendezvous." The exhibition included such automotive gems as the 1940 BMW Mille Miglia Touring Coupe, the 1977 Mercedes-Benz C111/III, Porsche's 356 Pre-A coupe of 1950, Petermax Müller's 1938 World Record Volkswagen, Das Auto magazine founder Paul Pietsch's 1952 Avus Coupe, and the Kamm K3 from 1938.
