Jigsaw puzzle with two adjacent pictures - has adjacent pieces along line of separation formed with corresponding cutting lines

摘要

The puzzle has pieces which are cut out so as to be able to be re-assembled to re-constitute a picture. It has at least two pictures placed adjacent to one another. The adjacent edges of the two pictures have pieces of equal length along the line of separation. In this way the cutting lines of the pieces of one picture correspond with those of the other picture. Single double pieces may substitute for two simple pieces along the line of separation.
