UK retailers Game and Gamestation have announced that customers who preorder a copy of Halo: Combat Evolved Anniversary will be able to get their hands on a special edition 24 page booklet featuring artwork from Halo's 10 year history.
The booklet contains a selection of artwork seen in the commercially available Halo: The Art of Building Worlds hardback book from Titan Books. It features concept art, landscapes seen in the games and the way Master Chief has evolved over the years.
At present, this preorder bonus has only been confirmed for UK retailers -- we'll be sure to update if we hear anything from North American stores. Don't forget that everyone who preorders Halo Anniversary also gets themselves some Xbox avatar armor and a special game-modifying skull to use during play, as outlined in this post from 343 Industries.
