Topps 1991 Toxic High School Sticker Packs Factory Sealed. This listing is for a single pack which will be shipped in a plain white envelope.  Packs are factory sealed and in good condition (not perfect). These aversion cards followed Garbage Pail Kids Launch in the mid 1980s and never quite gained the same traction GPK Packs have garnered. Artwork is excellent. There are a couple photos here of what some of the cards actually look like in case you haven't seen them. The cards are actually stickers.
