Patented in America in 1965, this puzzle was originally created by Joseph L. Litle. The idea to make this puzzle came to me after playing with a wooden copy built for me by my close, but now deceased friend, Tadao Muroi. The proportions have been changed considerably from the original plan in this new version. With this puzzle being styled after a violin and its strings, the key word here is "strings." Provides puzzles for older children and adults which are solved using a blend of inspiration and logic. The challenge is to take the puzzle apart and put it back together. Simple, yet so deep, you will need your hands and your brain on board to solve the huzzle puzzles! Develops imagination and creativity A great gift idea Ages 8+
