Geometric Model by A. Harry Wheeler, Stymmetrical Icosahedron

Geometric Model by A. Harry Wheeler, Stymmetrical Icosahedron

Usage conditions apply
This cut and glued white paper model has a three-sided irregular pyramid attached to each of the twelve pentagonal sides of a regular dodecahedron. The small triangular face of each pyramid is in the same plane as an adjacent pentagon. The two larger faces of each pyramid are in the same plane as two larger faces of other pyramids, making for an addition (12) (2) /3 or eight faces. Perhaps for this reason, Wheeler considered the model an icosahedron. A mark in pencil on the model reads: No. 411. Another pendil mark reads: Symmetrical (/) Icosahedron (/) II Species (/) March 24 (/) 1934.
