The original puzzle is called "Question du Lapin" made by WATILLIAUX around 1900. The puzzle was republished in cardboard in 1985 by a Dutch magazine "Margriet". They changed the flower and the flowerpot into a whale and a chicken.I made this on transparent overhead sheet. In 1993 you were still allowed to come with a copy.
