Since the Aurora Massacre, DC Comics and Warner Bros. suffered from marketing violence in both comic books and movies such as The Dark Knight Rises. The comic book that suffered the most was Batman Inc. with their Issue #3 that featured a classroom of children being held up by a woman with a gun. Due to this imagery, Issue #3 was delayed because it resembled too much of what happened at the Aurora Massacre in July. Now, comic book is behind in releasing issues. In October, Issue #4 will be coming out as well as Issue #5. So, everyone will be getting two issues on October 24th.
Enjoy the variant cover for Batman Inc #4 by Andy Clarke who has done the art for Batman #0 featuring all the Robins and Barbara Gordon as a back-up story.
