Tales of the Unexpected #57

A yellow-suited Space Ranger fires his delta ray at a looming blue creature on Jupiter's rocky surface — only to watch it split into two snarling, glowing monsters, each more menacing than the last. A small pink alien companion at his side delivers the alarming warning right there in the dialogue balloon: fire again and they'll keep doubling. Bob Brown's cover for this 1961 DC anthology gem captures a wonderfully diabolical sci-fi dilemma that perfectly embodies the era's imaginative storytelling spirit.
