In der Deutschen Anleitung finden sich folgende Angaben betreffend Original Design und Vertriebsquellen:
- Educational Design, Inc. 47 West 13th St. New York, NY 10011; 1977
- Tree of Knowledge (Europe) c/o Tali Ltd. 37 Broadhurst Gardens, London N.W.6 England 3QT
   Tel. 017-486 4377
- Tree of Knowledge (1979) Kibbutz Yasur 20150, Israel; 1990

Es ist also fraglich, ob die Konstruktion aus Israel stammt, da das Copyright 1977 von Educational Systems NY beansprucht wird.
