This is a really fun Royal souvenir. This one is harder to find as it was made to commemorate the marriage of Diana Spencer and Prince Charles on 29th July 1981.
It takes the form of a Rubik's cube puzzle and it has portraits of the couple and the Union Jack. It is in excellent vintage condition and comes with its original box. The sectional images of Diana and Charles form a portrait that fills a full side of the puzzle.
This measures (in its original display box) 2 3/4 inches in height - and with the sides measuring 2 1/2 inches square.
A quirky item to add to your collection of vintage toys or Royal memorabilia. My asking price reflects its "as new" condition.
