1st story: "The Creature in the Velvet Cage!"
While visiting the Justice Society on Earth-2, the Justice League heroes learn the untold story of why the Sandman years ago returned to his original crime fighting costume. An experimental weapon in his arsenal had accidentally exploded, transforming his boy partner, Sandy, into a gigantic monster. Overcome with guilt, Sandman had destroyed his purple and gold costume, which had constantly reminded him of Sandy's plight. Imprisoning the monstrous boy in a chamber which held him unconscious, he had returned to action in his old gas-mask and double-breasted suit.
