notes: label: Description
content: This twenty-pointed hollow model has an underlying celluloid frame that holds twelve paper six-sided polyhedra. Each of these polyhedra has a triangular pyramid that points outward and a shallower triangular pyramid pointing inward held by the framework. The model also has twenty holes in the shape of regular pentagons. A typed paper tag reads: 422 (/) Ic. A pencil mark reads: 422. Another pencil mark reads: No. 423 [sic]. A mark in pen reads: Icosahedron (/) Derived (/) from (/) Five (/) Intersecting (/) Tetrahedra . Another mark in pen reads: A. Harry Wheeler (/) Aug-28, 1932.
