Alvin #15

This 1966 Dell issue plunges Alvin into spy-thriller territory with a cover that sets the stakes high: a villainous figure in a blue coat looms over a captive U.S. astronaut tied to a chair, while Alvin pleads for help — all as a newspaper headline announces the astronaut's scheduled blast-off. A smaller inset panel shows another alarmed character, underscoring just how much trouble our heroes are in. "The Great Spy Mystery" promises the kind of madcap, high-stakes fun that made Dell's humor comics a staple of 1960s kids' reading.
