This issue collected various stories featuring the Joker as a guest star during the bronze age period. It is most noticeable however for including a previously unpublished story originally created for the short-lived comic book series “The Joker”, that was published between 1975 and 1976. The series was cancelled with #9 but this never before seen #10 was set to be the first of a three-parter in which the Clown Prince of Crime was going to take on the Justice League.

Wonder Woman’s death in this story is surprisingly grim for a comic book which, at the time, was still considered a humble kids book.
