When DS was at that particular hurdle I found a trove of old Disney comics at Half Price Books for a quarter apiece. (Mostly Donald Duck, some Goofy etc.) He read them until they fell apart. He liked Peanuts at that stage too.

He then moved to Diary of a Wimpy Kid, still likes Big Nate. The Ellie McDoodle series is a lot like these, but about a girl.

He's over the intense need for pictures now, but for a while it drove my shopping.
