This game consists of six heavy cardboard game boards (8.5" by 6.5") and 54 heavy cardboard game pieces. Each board has nine squares, each with half an image of an object and an = sign with a number. Each game piece has the other half of the object and two numbers with either a +, - or x sign. The illustrations are all in a palette of oranges, blues and off-white. Exact age and manufacturer are unknown. The images of the vehicles suggest that this was probably produced in the 1930's. There is no game box. In very good condition; some very minor staining to the surfaces and several very small edge dents.
