JIGSAW Puzzles (JIG) are made as if cut or stamped into
pieces from a single complete object, and the principle objective is to restore
them to their unique original form.
A magnificent cabinet of five maps dissected along the boundaries, as an educational toy, was made by John Spilsbury in London around 1768. Spilsbury, as far as is currently known, was the inventor of the Jigsaw puzzle.
