Here's my take on JLA #50 blank cover for Hero Initiative.
Done with markers.
The Hero Initiative, a charity dedicated to helping comic creators in medical or financial need, most proudly announces their new partnership in the Justice League Of America #50 project with DC Comics. This is the first collaboration with DC comics ever and Hero is chomping at the bit to pull the collection together. The call has gone out and dozens of artists are putting pen to paper. DC has generously donated 100 blank-covered cardstock copies of Justice League Of America #50 to Hero, and work is being created by well-known stars such as Jim Lee, Alex Ross, George Perez, Jason Bone, Jim Valentino, and many many more.
