Adventure Comics #395

This July 1970 issue of Adventure Comics puts Supergirl front and center in a genuinely unsettling scenario: she faces off against a translucent, rhinoceros-like Kryptonian Thought-Beast whose glowing thought-screen reveals its terrifying intentions for her — a wonderfully eerie concept rendered with real atmosphere by cover penciler Curt Swan and inker Murphy Anderson. The thought bubble within the creature's screen vividly depicts Supergirl being overwhelmed by a solid, darkened version of the beast, while her caption poses the delicious question — are there really ghosts, or isn't there? Titled "The Heroine in the Haunted House!", this issue blends superhero action with old-fashioned spookiness in a way that makes it a standout slice of early-'70s DC storytelling.
