Of course your clue here was the bears, and a bit of poetic license as I was referring the three bears and the porridge.
I have a feeling we have had this set before but as I go back through the newsletters I will sort that out.
Ha.556 tells us that this set was also issued, in the very same month, with a different back by Nicolas Sarony, you can see the two headers in our composite photo. Strange that they should have gone to such elaborate effect.
But there is another difference between the two sets as well, and that is that our set has matt fronts and the Sarony are gloss.
