Boys' and Girls' March of Comics #327

In "The Sunken Stone Mystery," Fred Flintstone’s routine day off takes a surprising turn when a suspiciously sunken paving stone in front of Bedrock City Hall starts causing trips and falls. With the mayor’s scrutiny looming, Fred and Barney team up to fix the issue—only to uncover more than one problem, leading to a series of inventive, if clumsy, attempts at repair. Written by Vic Lockman and illustrated with lively detail by Phil De Lara, this 1969 adventure from Boys' and Girls' March of Comics #327 is a charming, lighthearted caper that highlights the duo’s teamwork and quick thinking, all under the crisp, colorful cover by De Lara.
