Superboy #115

Two scientists watch in alarm as Superboy becomes an unwilling nuclear reactor — the cover makes it startlingly clear, with an atomic explosion visible right through his chest cavity while flames erupt from his mouth. Cover pencils by Curt Swan and inks by George Klein give the scene a clean, vivid urgency that perfectly captures the wild Silver Age premise of "The Atomic Superboy!" This 1964 DC gem is a fine example of the era's gleeful willingness to put the Boy of Steel into the most outlandish scientific predicaments imaginable.
