This child's toy consists of a number of large cardboard cubes, printed with different designs. By arranging the cubes you can create a variety of pictures. Basically a very simple jigsaw idea.
The things that we liked about these is the paper engineering that has gone into the cardboard cubes. They come packed flat in a box, and when you take them out, they immediately pop up. The cubes have an elastic band inside, and this pulls the cube into its final shape. Once you have finished playing with the toy, the cubes can all be squashed flat again, and popped back into the box.
Tim bought this toy 20 years ago, and as far as we know, it is not currently available anywhere.
