Tales of the Unexpected #21

A green alien emissary gestures menacingly at a human prisoner behind bars, while two more eerie figures loom in the background window — it's a tense interplanetary standoff rendered in vivid late-1950s DC style. The cover's speech bubble warns that unless a captive called Zog is freed from an Earth prison, the human will face punishment on another world, teasing a cosmic hostage drama worthy of the title Tales of the Unexpected. Bob Brown's cover work delivers a genuinely unsettling scene that captures the era's fascination with outer-space intrigue at a crisp ten cents.
