>>529775I sold these kits in my father's bokstore in Germany. They were published by Benedikt Taschen, Cologne/Germany, nowadays a publisher extraordinaire, known and famous for his big art books. Initially he started as a comic books seller who step by step began to publish exciting books which were both cheap and good. The skeleton was part of his early projects. He also published a couple of books about M.C. Escher and comparable artists, including a book titled "Unmögliche Figuren" (Undecidable Figures). This books contained pre-cut parts - you could actually build these figures. I should still have a copy of this, but I have no idea where.
