Poster stamps, or Reklamemarken, were advertising labels or seals printed like postage stamps on perforated sheets of adhesive paper.
Widely used and extremely popular before World War I in Europe, especially in Germany, these little collectibles almost disappeared after World War II.
As music iconography, they are exemplified in a collection of recorder-themed poster stamps recently donated to the American Recorder Society by Ewald Henseler, the author of “Not postage stamps—but recorder poster stamps” (American recorder LIX/1 [spring 2018] pp. 32–39).
