Push-fit Jigsaw Puzzles
John Spilsbury of England made the first recorded jigsaw puzzle in the 1760s. The puzzle was a map of the world and was formed by Spilsbury attaching a map to a block of wood. Each country was cut out of the wood using a marquetry saw. This type of jigsaw puzzle was considered push-fit because the pieces fit together but did not interlock. The result was an expensive jigsaw puzzle reserved for the prosperous who could afford to purchase this luxury. It was also used as a teaching tool in educational settings.
