Mystery of the Pyramids. Columbus, UF Grant, ca. 1965. No matter which way the decorated canister is turned – right side up or upside down – the pyramid-shaped stack of graduated blocks inside stays right side up, in defiance of all physical laws. Large and small sizes included; the largest 6” high. Paint worn; good.
