Pelikan published in 1984, as a return to old values, a small booklet in 13.5 by 23.5 cm format with historical advertising stamps whose originals appeared around the turn of the 19th to 20th century. The booklet contains three sheets with twelve different seal stamps each in styles like Art Nouveau, Expressionism, Futurism and Art Deco; some are poster designs by graphic artists and painters of the time. Advertising stamps, occasionally also called seal stamps, had their heyday between the early 1890s and 1914 and were printed in millions in Germany. They were artistically designed pictorial marks given to customers for advertising purposes, usually in product reference; original advertising strategists expected the stamps to be glued onto letters and envelopes, contributing to brand spread. Already at their heyday they were a popular collecting object; after WWI cigarette cards largely displaced advertising stamps.
