Query: An Excellent Encyclopedia of the World of GI Joe

If you are a huge GI Joe fan (like myself), then this book is a must-have! The book outlines everything you ever wanted to know about the world of GI Joe cartoons & comics (including the first few comics currently written by Devil's Due Publishing). The author goes into great detail about analyzing each cartoon episode, outlining storylines including mistakes within the storylines and animation.If you never read the original Marvel comic series, the author does an excellent job of summarizing the entire comic book line from beginning to end.This book is an excellent book and is absolutely bargain priced.
