Rotadraw was voted the Educational Toy of the Year in Britain in 1969.
The new drawing tool featured a plastic stencil disc with a series of oddly-shaped slots. The child pinned the disc onto the paper and rotated it, filling in the slots in numbered order with the supplied pens.
When the numbers ran out there was a completed picture underneath the disc. The beauty was that there was no way to tell what was being drawn until the disc was taken away.
Rotadraw came in a number of themed sets including zoo animals, farm animals, pets, transport, soldiers, Disney cartoons, The Flintstones, the Magic Roundabout, Rupert the Bear and Super Soccer.
The kits came with six discs, pins, a drawing board and pad, a ballpoint pen and six felt tips. The original price was 17s. 11d.
