The Brave and the Bold #103

This 1972 team-up pairs Batman with the Metal Men in what the cover frames as a chilling robot uprising scenario — a rogue metallic figure grips Batman while demanding he push a button to "destroy all flesh-and-blood," with the silver form of Tina (Mercury's companion) reaching out in apparent desperation and a vision of an ordinary city street displayed on a screen above them. Nick Cardy's cover art crackles with urgent menace, balancing the robot threat's cold machinery against the very human stakes on the line. With Bob Haney writing and Bob Brown on interior art, "A Traitor Lurks Inside Earth!" promises the kind of wild, high-concept DC adventure that made The Brave and the Bold such a rewarding read.
