Query: The book on the subject, outstanding photography!

This will be the book on the subject for many years to come! 552 pages with full color/full page photos of the greatest Bowie knives ever made from the big collections. Not much text, very brief captions to the photos. Only 1,100 were printed, so it is very hard to find. Expect to pay over $300 for it, but it is well worth it!
