In the hands of dozens of writers and artists, DC Comics Justice League of America (JLA) has experienced moments that can be intensely personal or of great cosmic importance. The comic's ability to shift in tone has always kept the team interesting and reflects the changing tastes among the readers and the times when each moment occurred. The Justice League, the team also known as the World’s Greatest Super-Heroes, have flowered and foundered, seen their ranks swell and shrink, and risen and fallen in sales popularity, but remaining a fixture in pop cultures for decades. What you will see on the pages that follow are one hundred of the greatest moments, each one a piece of the mosaic that is the Justice League. From their first rallying issue to the League finally reaching the big screen in the 2017 feature film Justice League, the members and their stories has remained entertaining for readers and watchers . The selections of iconic comic moments to come were not chosen in a vacuum. Moments chosen consist of nominations from various Facebook fan groups as well as former JLA scribes Mark Waid, Kurt Busiek, J.M. DeMatteis, Bob Rozakis, Gerry Conway, Marv Wolfman and former DC editors Michael Eury and KC Carlson. Ace researcher and comics historian John Wells and current JLA editor Brian Cunningham also offered input on the most contemporary selections.
