Model for Projective Geometry by Richard P. Baker, Baker #103


This painted wire structure is a model for projective geometry. It shows four points projected to four points in different planes. A typed paper tag attached to one edge reads: No. 103 (/) 4 pts. to 4 pts. in diff. (/) planes. This is one of a series of models for projective geometry listed in Baker’s 1931 catalog. It sold for $5.00.
