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. Nowadays you have to participate with your own design.
Old puzzle. Copy produced by puzzle design Ton Delsing.9 cardboard pieces. The puzzle was patented in 1911, This variation on Thurston's puzzle was used as an advertisement for soap. The idea was to arrange the cards so that each center circle contained four different colors and each half circle contained two.
