I created a special Discworld Stamps jigsaw especially for the Flatalists on the Cunning Artificer's board. The picture is of an LBE (Little Brown Envelope) and a set of the original DW stamps.
This particular LBE (which I own) is the rarest of LBEs and the Holy Grail to Flatalists as only about 12 were ever made. They were created for Harper Collins launch of Going Postal and given as prizes to the best displays of Going Postal by bookstores in the US. Sharlene had her bookstore then and won one, which she gave to me.
Anyhow here's the jigsaw, which I've called Harper Collins.
