There are many very nice collector items for sale on the web. It is not done to browse and show them all, but every now and then I try to share the real special findings and combine them at this page. Whenever there is more to find from a particular artist I will create a seperate post.
These are true collectors items:
La Princesse Sonia (1932), Unter dem Hintern einer Frau (1975), Cruelle Despote (1936)
