Action Comics #258

The cover of this November 1959 issue says it all: Superman hurls a bubble containing a pleading Supergirl away from Earth, with speech balloons making the dramatic stakes unmistakable — she begs for another chance while he declares her exiled as a failure. Curt Swan and Stan Kaye deliver a genuinely striking image, with the rocky landscape and streaking motion lines lending real weight to the scene. Inside, Otto Binder and Jim Mooney bring the story "The Menace of the Cosmic Man!" to life, making this a compelling chapter in Supergirl's early adventures.
