Schulbibliothekarische Arbeitsstelle Frankfurt am Main [1] (Frankfurt, Germany)

This is amazing: The “Schulbibliothekarische Arbeitsstelle Frankfurt am Main” (school-librarian department Frankfurt am Main) in Germany is a departement, situated in the public library of the city, charged with the task to support every school library in the city (more than 200 schools, not all with a library). On thing the department does is purchasing the books the schools have selected, then outfitting and cataloging them, before sendig them to the schools. For this the departemend has a stamp for every school library it supports.

So, those are all those stamps, nearly 200 of them. The beauty of stamps…
