The Im Obersteg Collection at the Kunstmuseum Basel 

The Im Obersteg Collection is one of Switzerland's major private collections of Classical Modernism. Top works by world-renowned artists make up the high points of the collection: Marc Chagall, Pablo Picasso, as well as important work groups by Alexej von Jawlensky, Paul Klee, Chaïm Soutine und Bernard Buffet. The approximately 200 works have, since January 2004, been left to the Kunstmuseum Basel, where they are, in part, permanently exhibited.
