 Sure. So when I was writing my first book, With Great Power, which is about Stan Lee, I kind of ran into wondering about Steve Ditko, who is the illustrator of Spider-Man, and why no one ever talked about him. And he's only just now kind of credited as the illustrator and co-creator. You'll notice now in the Marvel movies, they finally slapped his name up with Stan Lee. But my illustrator, Lee Gatlin, kind of brought him up when we were working on this one.
