Finally a page with the miscellaneous bits and bobs associated with the Great Explorers menage-a-trois.

Visitors to the 2009 North American Discworld Convention held in Tempe, Arizona, were awarded a little freebie with the three stamps. It was quite simple; a cellophane envelope with a paper insert and the three stamps. No sports were included and the colours are within the spectrum of variation shown on the Varieties page. Indeed, because of the timing of these packs it is likely that these represent the first print colours of the issue.
Of interest to me is that it emphasises the Ankh-Morpork Trespassers Society, a reference to a passage in Unseen Academicals, and the statement that it is the Explorers Collection No 1. We are still awaiting No 2

How many collectors have one of these cheeky se-tenant strips in their collection?
