World's Finest Comics #143

In "The Feud Between Batman and Superman! Part I," a wounded Batman questions his worth when he realizes his lack of superpowers makes him feel useless—even as Superman tries to help. Taken to Kandor, where even the Man of Steel is powerless, Batman must confront his doubts in a world where strength isn’t measured by power alone. Written by Edmond Hamilton and brought to life by Curt Swan’s art and George Klein’s inks, this 1964 classic explores the heart of heroism with quiet intensity. The cover by Curt Swan and George Klein captures the tension between the two icons in a moment that defines their rivalry.
