"I still like looking at Ditko's stuff and think his work is valid. He's not a great drawer but he is clearly full of intense feelings and a lot of rage. Although his actual rendering skills aren't as strong as someone like Toth his ideas, feelings, and visual concepts are strong. This book [Mysterious Traveler] collects various sci-fi and horror comics he drew that are all pretty fun to look at and have neat visual ideas littered throughout." – Nick Gazin, VICE - Fantagraphics Books
