Detective Comics #377

In "The Riddler's Prison-Puzzle Problem!", Batman faces off against the Riddler, whose latest scheme hinges on a series of cryptic clues tied to a deceptively simple setup involving an old funnel and a ball of twine. Written by Gardner Fox and illustrated by Frank Springer, with inks by Sid Greene, the story unfolds with the Riddler’s trademark obsession with puzzles, testing Batman’s mind as much as his skills. The cover, by Irv Novick, captures the tension with a striking, stylized image of the two adversaries locked in their intellectual duel.
