Pythagorus illustration

An Illustration by J. A. Knapp on page 64 of An Encyclopedic Outline 
of Masonic, Hermetic, Qabbalistic and Rosicrucian Symbolic 
Philosophy, published by the Philosophical Research Society, is of 
Pythagorus holding a tetrahedron in his right hand. Can anyone find 
that illustration on the net to link to? I'd like to refer to it to 
make the point Bucky Fuller made in Synergetics about old trade 
secrets hidden with superstitious nonsense to confuse outsiders.
