notes: label: Description
content: This tan paper model has twelve points. Two, opposite one another, are at the vertex of pentagonal pyramids (the bases of the pyramids are withn the surface). Ten, going around the sides, are formed from two trapezoids and two triangles. The trapezoids meet in a short line and the base below each short line segment is a trapezoid (again within the surface). A mark on the object reads: Pentagonal (/) Trapezoidal (/) Dodecahedron (/) June-16-1931. A typed paper tag reads: DT2. A third mark is Wheeler's number for the model: 288
label: Description
