Cracked JACK or Soft Boiled SAM is card 58a/58b in the original second series.
Description[]
The card shows an egg-like kid cracked open with yellow yolk pouring out and a chick popping out of his head.
Parodies/Represents[]
The card possibly parodies the nursery rhyme Humpty Dumpty. This is rather interesting, because an episode of the Garbage Pail Kids Animated Series had the kids enter the nursery rhyme world and meet Humpty Dumpty's brother.
