This is another item that I played with at my grandma's house. It is quite old. I always found it challenging when I was little because depending on how I placed the cubes it would make one of six puzzles. Many times I would get frustrated with it and set it aside. The other day I got it out and the girls did a few of the puzzles. I'd love to know how old it is! I did notice on the back that it is made in Germany. Has anyone seen one like this?
