  • Patent number: 5149570
    Abstract: A jigsaw puzzle having self-adhesive pieces is provided. Each piece has a first sheet with a pictorial image on one surface, and an adhesive sheet bonded to the opposing surface. The adhesive sheet has a pressure sensitive adhesive surface opposite the first sheet. A release sheet substantially covers the pressure sensitive adhesive surface and is readily removable by means of a pull flap to expose the pressure sensitive adhesive surface. In practice, the individual puzzle pieces can be simultaneously assembled on and bonded to a mounting board. The mounting board can then be framed and hung for viewing.
