MY nephew is 4 years old and he is very into Superman, the Flash, and Batman. He got a small superman comic book from school and the art isn't all that good, but he carries it around with him all day. I've been looking for books on amazon but its hard to pick anything without seeing the inside. He's not hardly reading yet, i just want something with good artwork he can look at.

I bought the first Superman Adventures book. We'll see how that works out. Any recommendations?
