An Unusual Piece of Mercedes-Benz Literature: Stamps and History

Hi folks -- I saw this on Ebay this morning and thought it was rather unique, in that I have never sen this brochure before, That stamps are not particularly expensive, but it is a nice touch in making M-B owners feel that they are special, and are a part of a larger historical context. If I am not mistaken, the  stamps were issued in the late 1950s. At about the same time M-B also sponsored a Riverside Records (see a past post) LP record on the sounds of its 1930s race cars also directed towards owners.
