Most unusual puzzle combining elements of jigsaw and cross word puzzles published by The Cross Jig Publishing Co, Meriden, CT as Puzzle No. 1 in 1932 c. Die cut from cardboard along the sides of the squares. Definitions across and down are printed on the inside cover in the same sequence as traditional crossword puzzles but with the number of letters indicated for each word. The shape of the pieces is more similar to some forms of mechanical puzzles than jigsaw puzzles. The puzzle can be worked on the inside of the box bottom. A new Cross-Jig Puzzle was to be issued every Tuesday. However, this is the only one currently known to exist, so few were actually issued and probably none after the first week. Too bad, as our sons had a lot of fun assembling the puzzle one evening during a family vacation. The picture displayed has 2 pieces switched; did you find them before reading this?
