Geometric Model by C. D. Wesson, a Student of A. Harry Wheeler, Great Icosahedron

Usage conditions apply
The great icosahedron is a regular polyhedron formed from twenty intersecting equilateral triangles which combine to produce a figure with twelve points. The surface was first described by the Frenchman Louis Poinsot in 1809 and is now known as a Kepler-Poinsot solid. This is a cut and folded paper version of the surface. A mark on it reads: C.D. Wesson (/) 6/15/16. Another mark reads: H.S. of C. (/) 1916. This model was made while A. Harry Wheeler was teaching mathematics at the High School of Commerce in Worcester.
The model is presently (February, 2019) in pieces, suggesting how it would have been assembled.
