The previous year's set of Comic Book Heroes stickers having been successful, Topps decided to turn out basically more of the very same thing. This set contains most of the popular Marvel characters who were active in their comics at the time.
The stickers were the same die-cut images taken from previously used artwork, with a 'funny' word balloon attached. Note that there were variations in the cpations that went with each superhero character. In addition, there were nine puzzle piece cards that, when put together, formed an image of the cover to Marvel's Conan the Barbarian #1 comic; the backs of these were checklists. The sticker backs were either blank white, or featured instructions on how to peel the sticker.
There were three pack variations, each showing a picture of either Spider-Man, the Hulk, or Captain America.
