Rare cube-style puzzle map of the United States

"[Set of 6 Puzzle Maps]", Anon.

This extraordinary and complete puzzle consisting of six maps, including the United States, and five regional maps. The map are on the sides of 20 wooden cubes. Getting the puzzles in the correct order is not easy and reminds one of working with a Rubik's Cube. The cubes fit into the original wooden box that has the guide map of the U.S. pasted on the cover with a decorative border mounted around the edges. The other sample/guide maps store in the box, above the wooden cubes. A rare cartographic curiosity that has survived fairly well given its purpose as a game. Not dated and mapmaker is unknown. Correctly arranged, the cubes make the following maps, each measuring approximately 8.5" x 6.5".
