How have artists' styles evolved in Batman comic book cover art over the decades?

Batman cover art has evolved dramatically. Early covers (Golden Age) were often simple and focused on heroic poses. The Silver Age brought more dynamic action and sophisticated layouts. The Bronze Age saw a rise in gritty realism and darker tones, with artists like Neal Adams. The Modern Age (post-Crisis) has seen a resurgence of diverse styles, from Jim Lee's detailed realism to more stylized approaches by artists like Scott Snyder and Greg Capullo. The trend continues towards varied and visually impactful designs.
