Models for Descriptive Geometry by A. Jullien

Description
This wooden box holds thirty models (called reliefs in French). Each is a folded card held in place by a metal mount that can rest in the palm of your hand. Each model depicts a concept of descriptive geometry. Wires and string show the geometric concepts in three dimensions and the two projections are depicted on the horizontal and vertical portion of the card. The strings are held in place by small washers on the back of the cards.
Individual models are described in records 1986.0885.01.01 through 1986.0885.01.30. A related manual is 1986.0885.02.
