The Igors are a special caste of humans originating in Überwald, but lately found elsewhere such as Ankh-Morpork. While not a stamp issuing authority they have contributed to flataly in a few ways. Most notable was when they used their skills with needle and thread to create the Thitched-up By Igorth stamps - made up of many small pieces of other stamps from across Discworld. They appeared in the LBE of that name during the Year of the Frog Ascendant. A final offering was a Hogswatch version later that year. See if you can work out which stamps contributed to each of the Igor Stamps, and check your answers in the Discworld Stamp Catalogue.

Collectors might like to include the two Igor associated postal labels, not shown to scale.

The Igors have also led to an Ankh-Morpork revenue stamp, the 7p Post Mortem tax stamp. This appeared in a limited edition Igor Assurance Company pack which was associated with the Igor-2-Igor organ donation and swap scheme. What goes around comes around. Apart from the stamp, there was a donor card, policy document, receipt and more. Click on the documents to see a larger version of each.
