Query: a excellant book to check out for die hard knight fans

I got this book (under a different cover and name) at barnes and nobles and found this particular book at a border's book store. It has excellant illustrations and tons of useful information on the changing era of the knight and how his armor tangressed over the period. Tells the history of the knight from his humble beginings to its climatic end when the use of firearms made the knight absolutly extinct. Defently a worthwhile book to get for any fan to own
