I pre-ordered this book about 5 months ago & it just arrived. The original description detailed it as a study of the history of the character. That it is. But I had no idea it was gonna be a 14" art book! The updated description notes this, but it was a pleasant surprise. This thing is sweet!

It's about $28 on Amazon & totally worth it if you're a fan.
