100 blank-covered cardstock copies of the new HULK #1 were donated to the Hero Initiative for a Hulk-centric "Ultimate 100" and dozens of artists have put pen to paper. Artists involved include well-known Hulk vets such as Sal Buscema, Mike Deodato Jr., Ron Garney, Ed McGuinness, Don Perlin, Herb Trimpe, Ron Wilson, and more. In addition, Marvel superstars such as J. Scott Campbell, John Cassaday, Frank Cho, David Finch, Joe Quesada and John Romita Sr. have stepped up to add their own take on ol' Greenskin. All 100 HULK #1 covers were on display for the first and only time at a gala "Green Room" event on Thursday night, June 26 during Wizard World Chicago, but you can see them all here on Marvel.com!
