While I enjoyed this book, it is a highly sanitized and Disney-fied version of Marvel history. No talks of Simon & Kirby leaving due to being cheated out of their share of Captain America Comics profits, no mention as to why Ditko and then Kirby left Marvel at the height of their popularities, no mention of just how Marvel managed to hang on to Captain America, Human Torch, Sub-Mariner in the late 60s and even gained the trademark to Captain Marvel, no creative difference issues going on in the Jim Shooter era, none of the Kirby artwork returns debacle, etc. Everything was painted over with a gloss.
Despite this gloss, the information was mostly acccurate. It was a brisk read and the included illustrations and photos were nice. The captions needed some standardization and proofing since some were misleading including the artists credits. It is a very good overview of Marvel history for the amount of pages.
