To show relationships among planes and angles, A. H. Wheeler designed a series of what he called platform models. All of these had a rectangular platform, with other segments (often other rectangles) secured to it.
This tan paper model shows the intersection of four planes. Two planes are movable, three are perpendicular to the base.
A tag on the model reads: PRP-L*. Another tag reads: Pat 1, 192, 483.
