This twenty-pointed hollow model has an underlying celluloid frame that holds twenty 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 twelve holes in the shape of regular pentagons. A typed paper tag reads: 423 (/) Ic. A pencil mark reads: Sept 6-1932 (/) No 423. Another pencil mark reads: No. 3 5 6' 9 10.
