This book was amazing for all comic book lovers! It provided amazing illustrations that were really detailed & portrayed the superheroes perfectly. It even had some comic snippets which were really enjoyable. It gave really cool history about the making of these superheroes & referenced them in case you wanted to learn more about them! It's nice for people who haven't read comics (like me) as it introduces the characters nicely. It even shed light on some of the lesser known superheroes. It provides a nice timeline & you would learn things you never would of about these really well known characters! It's a fast read & really enjoyable. My brother who loves superheroes, is reading it now & is enjoying it more than me!
