I got this a couple of weeks back but forgot to comment on it. I figured since I like Transformers so much I should pick it up and learn some stuff I didn't know about them. The book comes in a sturdy glossy cardboard sleeve. The book itself is a high quality hardcover. Inside you will find TF history, pictures of prototypes and replicas of the decoder and tech specs and toy catalogs. Spans from the very first Diaclones to the Movieverse stuff. Very well done and recommended.
