In the maker's words

RELEASED: 12.18.2005 PRODUCED: 12 Copies DESIGNER: David Singmaster CRAFTSMAN: John Devost MATERIAL: Lacewood, Macassar Ebony Box and Jatoba Pieces COMMENTS: Consisting of twenty five 1x3x4 pieces packed into a 5x5x12 box, this packing puzzle was designed by Mr. David Singmaster around 1970. It is the result of a search for the smallest non-trivial box packing problem using uniform pieces. 22 solutions are possible. The construction of this puzzle is top notch. Attention to detail shows in every step. The mitered corners are reinforced with solid Ebony slipfeathers which not only strengthen the joint but also add a decorative touch. Each puzzle piece is individually sanded and finished. Each piece is signed. 19 copies made for sale. SIZE: 1.75" X 4.5" PRICE: $69 (SOLD OUT) This item is sold out and no longer available.
