If you're a fan of lucha libre (particularly the glory days of Santo, Blue Demon and Mil Mascaras), it's hard to go wrong with this book. There are several high-quality reproductions of lobby cards and movie posters from the 1950s through the 1970s as well as a generous assortment of full-page photographs. Many of the photos were taken specifically for this book. You'll also find profiles of the Guerrero family, various other wrestling families, and some of the most heartfelt and sincere text ever written about the sport of professional wrestling. Kurt Angle's introduction is one of the best I've ever read in any sports book, period.
What's missing? The recent rise in strong, popular female wrestlers such as Dark Angel and Lady Apache, for starters. And if only the book had a sort of appendix listing the title-holders for CMLL and AAA and the lengths of their reigns!
That said, this is as perfect a book about lucha libre as you could ask for otherwise and unlike some treatments of the subject this is a book written from the perspective of someone who isn't trying to create an ironic quasi-anthropological treatment. This is written by someone who genuinely loves not only the sport of lucha libre, but its pop-culture spinoffs and its loyal fandom. This is well-worth your money!
