This is a well made version from plastic of a Bill Cutler design, about 5" by 5" by 2" , made by Ishi.The puzzle, looks simple from the top, but is extremely difficult to do (surprisingly). I did it once;it took me about 1/2 a day, and I haven't taken it apart since.

This puzzle -- The Pearl in the Shell Puzzle by Bill Cutler for IPP 26 was from the Boston Puzzle party. Although a somewhat smallpuzzle, it is about 4 1/2 " at the widest point. The puzzle is to take apart (dissect) and to rearrange the "pearl" into the shell ... It is beautifully made - almost a work of art.

This is a one-of-a-kind, experimental design that Stewart Coffin himself made in 2006.It is a 3x4x4 polycube puzzle similar to his convolution or involute cube puzzles.Made of maple, padauk, purpleheart and yellowwood.Comes with his original note sheet and solution.

Maker - Pelikan The design was driven by the admiration of geometrical shapes, especially compounds of polyhedra. The mix of two cubes has not only a surprisingly new interlocking principle, but its 3D shape is also a pleasure to watch. IPP22 design competition entry

Maker: PelikanNotes: 12 identically pieces form the shape of three intersecting cubes (inspired by M.C. Escher). Made in three fancy woods.On Jan. 14, 2008 10:31:31, the following description has been added:I forgot to mention that this is a design by Rik Brouwer, but you probably knew that...

Another early Eric Fuller work. This is harder to put together than to take apart. The cube does not really hold together, so you have to be careful when holding it. However, the wood used was a very high quality one.

This is a vintage 4-Leaf Clover Keychain Puzzle from the 1950's. Says "GOOD LUCK" in large letters and in small letters, "made in USA" and "PAT PEND". In excellent condition except for some bleeding of the orange plastic into neighboring pieces typical of the orange plastic used at this time. Normally this horseshoe was marketed with a horse head in the center, but this is a much rarer version with a clover leaf instead.

This is a 3D plastic puzzle of a Big Mac Burger put out by McDonald's many years ago. It is made of durable hard plastic and is in excellent condition. I was told that this was never marketed in the USA.

This is a miniature version of the jeep keychain puzzle and was made in the 1960s. It is complete and in excellent condition.
