Bat-Manga!(1966)

Batman

In the 1960s, during the height of Bat-mania, mangaka Jiro Kuwata was commissioned to write and draw a series of original Batman comics for the Japanese market. Many Western readers were only recently introduced to the existence of this unique take on the Caped Crusader. Now DC Comics presents the series in its entirety for the first time, fully translated and unabridged!
