Over two decades ago,Jim Lee was already a legend in the comedian book industry from his hasten on the X-Men and co-founding Image Comics. In 1998, Lee sold his studio, or Wildstorm,to DC Comics in order to focus on illustrating comics again. While he worked on a few projects in the intervening years, it wasn’t until 2002 that readers were able to enjoy his work on a monthly basis again.
