This is a miniature version of the jeep keychain puzzle and was made in the 1960s. It is complete and in excellent condition. This auction is for the MINIATURE VERSION ONLY, the large (typical) version is just shown for comparison. It measures only 1 inch (2.5cm) in length, including the keychain loop, and is one of at least 8 different rare miniature versions of common keychain puzzles.

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 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.

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

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 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.

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 puzzle, I got a long time ago, but was never brave enough to take apart. It is about 3" on a side, and consists ofwooden L pieces, and has metal bars that inhibit the position of the wooden blocks from being put together into the box. I was afraid if i took it apart, it would never get together again.. It is nicely made, and I think is quite difficult to get together again.So, good luck if you are braver and smarter than me..On Jan. 22, 2008 13:24:31, the following description has been adde...

Stewart Coffin wooden tray puzzle: "Few Tiles." Fit the four pieces into the tray. The tray opening is not square. Each of the pieces has two corners with 90° angles and each can be flipped over. A very difficult puzzle. Number 133 in Stewart's numbering system. Woods used are Baltic Birch and Mahogany.

The Melting Block wooden puzzle designed by Thomas H. O'Beirne and crafted by Jerry McFarland (2000). Fit the 9 pieces into the wooden box, so that the wood is flush at the top; creating a regular rectangular solid with no internal voids. Quite a remarkable dissection.
