What did Santa See?

This was the title of a pair of jigsaws where we only had a picture for one - the other one was called a Wasjig - and the two jigsaws are linked! The picture for this one was on the box - but we had to deduce the picture for the other one. That was quite fun, but obviously took a lot longer than the one for which we had the picture, When I give it away I had decided to enclose a photo of the picture - but perhaps that would spoil the fun??
