Undertaker has been through a hell of a lot of changes over the years, and every single iteration of the character has been meaningful and has had a major impact on WWF/WWE television. It'll be interesting to see if this new book takes into account all the different guises that The Undertaker has had over the years. From mute, slow-moving zombie and infernal overlord, to bad ass biker and supernatural wonder, there isn't much ground Mark Calaway hasn't covered whilst performing as 'Taker, so there's a lot of interesting stories which could be explored throughout the new book. Better yet, different sketches could be displayed, showing different prototypes for Undertaker's outfits and overall look. This is the perfect opportunity for WWE to show a side of The Undertaker which fans may not have seen before. If this book is expected to be an exhaustive look at everything the character means to the company, and wrestling as a whole, there should be some hidden gems in there which could show proposed different looks for the man.
