In 1941, the world was introduced to Captain America. A patriotic superhero that fought during World War 2 and has had an enduring legacy that still continues to this day, with a range of comics, action figures, movies and more.
Captain America - The Ultimate Guide to the First Avenger was published in 2016 by Dorling Kindersley. It was written by Matt Forbeck, Alan Cowsill and Daniel Wallace, with a special foreword by Stan "The Man" Lee.
The book itself covers everything you needed to know about Cap in a comic sense. It covers his inception in 1941, right through to the start of Sam Wilson's career as Cap. The book starts off with some basic information about Cap himself, all the different incarnations of the character throughout the 616 universe, as well as Ultimates. It also takes a look at some of his key allies and enemies.
This is where the real meat and potatoes of the book comes into play. The book talks about each decade in turn, as well as showing key events and key comic issues from that decade. It covers the main 616 cap run, Avengers and the Ultimate universe as well. This is where fans of all levels can learn some interesting facts about Cap and his Universe, such as how Zemo's mask got stuck to his face or the origins of the Red Skull or even how Bucky became the Winter Soldier.
While this book is aimed at 10 year old children, who may be interested in Cap thanks to the MCU, I feel that this book isn't really aimed that way. I feel it's more aimed at fans of Marvel Comics, thanks to the level of detail put in and that it only covers comic exploits, going back to 1941. Like all of the DK Marvel guides, I highly recommend this for any Marvel fan out there.
