Superman: The Man of Steel is a monthly American comic book series that ran for 136 issues from 1991 to 2003, featuring Superman and published by DC Comics. As a result of introducing this series alongside its already existing titles, DC Comics was able to publish a new Superman comic each week. Included in these 136 issues were two special issues: #0 and #1,000,000, which were tie-ins to Zero Hour: Crisis in Time and DC One Million, respectively.
