The globe is rotationally molded of iron particles and a plastisol of polyvinyl chloride and has embossed therein, from the mold, lines of longitude and latitude. Two or more layers of magnetized puzzle pieces are formed by printing their indicia on flat, soft, magnetized thermo plastic sheets and then die cut. The indicia is printed such that, when necessary, successive layers of puzzle pieces have their magnets aligned so that specific pieces adhere to specific places on pieces of adjacent layers. When necessary, the pieces are heat formed to conform to the globe shape. Preferably, the first layer contains continental and longitude and latitude information; the second layer, geologic features; and the third layer, political information. The globe stand has a recess therein, the bottom of which is of the same curvature as the globe and may incorporate or have sprayed on iron containing material so that the puzzle pieces may be conveniently stored there when not applied to the globe.
A puzzle comprising:
In a magnetic puzzle comprising a substantially continuous ferromagnetic substrate and two or more layers of flexible plastic magnetic puzzle pieces incorporating magnets having poles oriented in lines in said layer and adapted to be magnetically affixed to said ferromagnetic substrate or to a prior layer, the improvement wherein poles of said successive layers are aligned such that pieces from successive layers can be laid over each other in predetermined positions with the poles of said second layer on top of the poles in said first layer and wherein said magnets are aligned with the north and south poles of the magnets in said layers opposite to each other.
