Collectable Pokémon sticker-cards from Merlin, a subsidiary of Topps, released for the UK market from 1999 to 2006. Ten sets in all — seven numbered series plus three additional releases — sold in packs with companion albums. The trademark year on the back of each card is the way to tell which set it belongs to.
