Celebrate the career of a true Marvel Visionary! Best known as the co-creator of the amazing Spider-Man, Steve Ditko illustrated Spidey's adventures for four years and introduced dozens of classic villains. But even as he infused Spider-Man's world with grounded realism, Ditko took readers on mind-bending romps through twisted and mystical realms with another massively popular co-creation, Doctor Strange! Plus, Ditko's unmatched creative vision is on full display with the debuts of Squirrel Girl and Speedball - and scores of rarely seen fantasy and sci-fi work from Marvel's Atlas Era!
