We are happy to announce that the foundation has received an other painting by Peter Birkhäuser in March 2015 for it's collection. The painting «Der dunkle Bruder» (The Dark Brother) form 1961 was located for about 50 years in England. It hung recently in the C.G. Jung-Club in London. The foundation is very grateful for the donation of this fascinating painting.

Read more about it in the book Der rote Faden (2013) on page 170.
