Adventure Comics #168

A young would-be detective — magnifying glass in hand and a copy of "How to Be a Good Detective" tucked under his arm — has apparently cracked the case of a lifetime, boldly declaring "Superboy is Clark Kent!" while Superboy himself soars overhead and a startled girl looks on. Win Mortimer's cover perfectly captures the delightful tension of a kid who thinks he's outsmarted the Boy of Steel, setting up the story "The Boy Who Outsmarted Superboy" with a smile and genuine dramatic stakes. At 52 big pages for just a dime, this September 1951 issue of Adventure Comics delivers the kind of clever, lighthearted fun that made DC's early Silver Age output so endearing.
