I still have the original World of Warcraft one from when it first came out, and then 2 more during Burning Crusade that I got in the first version of the BattleChest.
Those two were slightly smaller, where the original one was nearly an inch thick and full of info about all the zones, quests, dungeons and raids and even gear from top content at the time.
It's currently in my computer room beside my game boxes, I've kept them all :D
