Abstract
The jigsaw puzzle according to the present invention comprises a substrate and transparent member. The substrate has a painting, photograph or pattern provided on at least the first side thereof and is cut into a multiple of irregular, interlocking pieces. The transparent member has marked thereon a figure which is to conceal at least a part of the cut lines in the substrate, and is to be disposed on the first side of the substrate. Since the zigzag cut lines in the substrate are concealed by the figure marked on the transparent member, the jigsaw puzzle having the picture thus reproduced can be an improved interior decoration.
