The Flash #141

This December 1963 issue from DC throws down a genuine gauntlet right on the cover: a bold "Challenge to the Reader!" invites you to match wits with the villainous Top and unravel "The Mystery of Flash's Third Identity!" The cover, penciled by Carmine Infantino and inked by Murphy Anderson, is a clever visual puzzle — the Scarlet Speedster races alongside a civilian man and woman, while a mysterious white silhouette filled only with a question mark teases the unknown identity, and a top panel shows a bespectacled figure insisting he doesn't know Flash's civilian identity — but he does know his new one. Written by John Broome with interior art by Infantino and inker Joe Giella, this is Silver Age DC storytelling at its most playfully engaging, pulling readers directly into the mystery rather than just watching from the sidelines.
