Super brain teaser!
This is what kids played with in the car before the Nintendo Gameboy was invented.
Copyrighted 1977 on the package and 1978 on the toy itself, this sliding puzzle is about 4″ wide by 4-3/4″ high and was released by American Publishing Corporation of Massachusetts and made in Hong Kong. It features Neal Adams art based on his iconic comic book cover from Superman #233. This art shows up quite a bit in licensed products of the period, probably because it’s completely awesome.
The card is bilingual English and French so it could be sold in the Canadian market. The back of the card is blank.
