In 1973, Topps reinvented wacky packs with a new format. Instead of perforations, every image was on a self-adhesive sticker-back card. The new cards where now called, Topps' Wacky Packages. Jay Lynch, a comics legend responsible for many of the Bazooka Joe cartoons, was also chiefly responsible for the art and concepts of Wacky Packages. These cards are referred to as the Original Series and have some of the best art work.
