Zag-Zaw line of puzzles was first produced in 1909, all incorporate figurals or whimsies, sold in red or orange boxes with labels on the side or bottom of the box, most without guide pictures. Initially cut non-interlocking but by 1930's became more so. Puzzles have a different cuts so that the same image will come in several versions which means that missing pieces can not be taken from other puzzles with the same image.
