Book excerpt: A visual history of one of Marvel's major brands: The Avengers. The book will trace the evolution of Thor, Iron Man, the Hulk and Captain America from comic book issue No. 1 in 1963, through their incarnations in film, animation and merchandise, to their current blockbuster status. As with Alien Vault and Terminator Vault it will feature rare and unseen artwork, and 10 pieces of removable memorabilia for fans to remove and examine. Published ahead of the second Avengers movie (which goes on general release in Summer 2015) the book will be a deluxe, official gift for film and comics fans alike.
