For sale is an original Cast Oskar Puzzle (Hanayama). This was Hanayama’s very first cast puzzle. It was designed by renowned Dutch puzzle maker Oskar van Deventer in 1987 and produced in 1988.

I discovered this online. I made a copy in the original colors. Not out of cardboard, but on transparent film. I also made a box that was as original as possible. Unfortunately, the original edition comes with a solution.Place the pieces perfectly on top of each other and find the rabbit.

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.
