If you will find yourself in the vicinity of  Ingolstadt, Germany, in the next month or so, you might consider stopping by the Museum Shop at the Audi Museum Mobile to pick up a copy of Audi Tradition’s stunning 2011 calendar, where it is exclusively being sold for €29.90, or roughly $40.

Called Time Warp: Auto Union Silver Arrows on the Historic Race Tracks, this collectible calendar was beautifully photographed by Stefan Warter. It features 13 gripping images of Audi’s six original and recreation Auto Union racers on nine of the European race tracks where they originally ran in the 1930s and 1940s.

Details and more images can be seen at Audi fan site Fourtitude.com.
