Remmember when Topps Garbage pail kids sticker cards were popular about 20+ years ago?. Teachers were forced to ban these in schools. Making these gross and ugly stickers a news worthy item. Today they are back, and sought after by the 40 something crowd looking to re-capture what they had in grade school. These collectors not only what them, but look to build a set in perfect condition. PSA graded GPK singles are the new rage and look to be the future of collecting. Most of the GPK singles were played with and have normal wear and tear. The PSA 9 and 10 examples are very RARE, grab them when you can.
