The objective is to fit all the pieces in the large square opening. There is only 1 solution and it is very difficult to find.  Packaged the puzzle unsolved, but the solution is provided.  Made from precision cut woods with at least 4 different woods in each puzzle. Ash, Maple, Walnut, Oak, Mahogany, Birch, Cherry, Alder, and other woods may be used with each puzzle have a little unique look. The pieces are very strong at 1/4" thick and have a nice finish. I also laser engraved the relative size of each piece on the piece itself, which may be helpful to you folks who want to attack this analytically. It also makes identifying the pieces easier if you just want to use the instructions to solve it. Originally designed in 1933 by Theodore Edison, son of the famous inventor Thomas Edison. Released October 2012.
