Superman #15

In "The Menace of Mr. Mxyzptlk!", a bored Superboy stumbles into a trio of small, seemingly harmless feats—one for a boy named Jo, another for a girl named Lila, and a third for a mysterious stranger—unaware that each act will ripple into his future. Written by Otto Binder and illustrated by Al Plastino, this 1959 classic captures the early days of the Man of Steel with charm and whimsy, while Curt Swan’s dynamic cover brings a touch of timeless flair.
