Fifty years ago, Batgirl made her Million Dollar Debut taking down the nefarious Killer Moth. And ever since, the butt-kicking hero has been a vital part of Batman''s team and a role model for girls everywhere, squaring off against mobsters, assassins, super-villains and more. Though many young women have worn the cowl—from unassuming librarian Barbara Gordon to deadly mute assassin Cassandra Cain to teen vigilante Stephanie Brown—all have made their distinct mark on the DC Universe. Now BATGIRL: A CELEBRATION OF 50 YEARS collects all the greatest triumphs and most tragic moments of the many Batgirls in one volume, offering a crash course in the character, from Babs'' first appearance by Gardner Fox and Carmine Infantino to her modern-day adventures by Cameron Stewart, Brenden Fletcher, Babs Tarr, Gail Simone and more.
