Detective Comics #121 (1947)

In Detective Comics #121, we see Batman and Robin come to the aid of none other than Commissioner Gordon himself. The dynamic duo is called to GCPD headquarters where they discover that Gordon has been unjustly demoted to a beat cop and stripped of his position as Batman's deputy. The mayor is behind this sudden change of events, but his motivations remain a mystery. Along with this thrilling main story, the issue also features Slam Bradley in "The Case Without a Key," Air Wave in "Happy Jail-Day to You," and a full-text story called "The Pink Sheet" by Dalton Warren. Plus, there are humor strips from Three Ring Binks and Morton, and even a tale of adventure from the Boy Commandos in "The Phantom Express."
