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. 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.
