The Kellenberger Collection is one of the oldest still active private poster collections worldwide. The owner Eric Kellenberger started in the mid 1960ies as a young Architect, searching for quality interior decorations, focusing on colorful images of strong artistic expression at affordable prices. Advertising posters matched perfectly. Since then, Eric Kellenberger organized or supplied fifteen mayor international poster exhibitions in Switzerland, France, Germany, USA, and Japan (catalogues). He exhibited, most successfully, since the early 1980ies, at the International Vintage Poster Fairs, in about 10 mayor American cities. He is one of the founding members of the IVPDA, since 1996.
