The world’s first official postage stamp was issued in May 1840: the legendary “One Penny Black” with the profile of the Queen of England. The new payment system in the field of logistics by Sir Rowland Hill quickly gained hold all around the world. For the first time this publication discusses the significance and functions of postage stamps as prominently visible elements of communication design. The expressiveness inherent in the small-sized images and the very peculiar and heterogeneous image vocabulary of this medium of mass culture is analyzed by means of more than 40 designs by Hans Günter Schmitz. The book also presents concepts that were not implemented, in addition to sketches, studies, and variations – from Adenauer to the film festival Berlinale, from a mathematicians’ congress to the famous Wuppertal suspension railway.
