In "Torso le monstre dévoreur," Jimmy Olsen accidentally activates a time machine and finds himself in Krypton’s past, where he ends up babysitting baby Superman. Though Jimmy’s memory of the adventure fades upon returning to his own time, the Man of Steel—now grown—still remembers every moment. Written by Otto Binder and illustrated by Curt Swan with inks by Ray Burnley, this 1965 tale features a cover by Curt Swan and George Klein.
