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 word here is...'string'.
