are a series of trading cards and stickers featuring parodies of North American consumer products. The cards were produced by the Topps Company beginning in 1967, usually in a sticker format. The original series sold for two years, and the concept proved popular enough that it has been revived every few years since. They came to be known generically as Wacky Packs, Wacky Packies, Wackies and Wackys. According to trader legend, the product parodies once outsold Topps baseball cards.
