Another great work in the K21 is "Mann und Maus" by Katharina Fritsch. There is a picture of this work and another work ("Monk, Doctor, Dealer") that I found here - http://members.virtualtourist.com/m/p/m/1c620a/
PS Beuys is shit. Indescribably shit.
Please also see the gallery of photos we took of the work "Volume" that we saw at the V&A in Dec 2006;
