House of Secrets #6

This October 1957 DC mystery title delivers a wonderfully tense cover by Nick Cardy: a massive gorilla clutches what appears to be a stolen formula while looming on a ledge outside a laboratory window, as two alarmed men — one armed with a gun — argue over whether to shoot the creature before it escapes. The bold "Experiment 1000!" banner and the frantic speech bubbles give the scene an irresistible pulpy urgency that perfectly captures the era's taste for science-gone-wrong thrills. Inside, Mort Meskin brings his distinctive linework to the stories, making this a solid showcase of mid-fifties DC storytelling craft at a dime a copy.
