Guitar Collector Forum

I have "New Musical Express 1974 Hot Rock guide" book which has two pages of Gibson's Guitars: A History, with another two pages of photos one with Wishbone Ash Andy Power with the Gibson Flying V, and other with Alvin lee-on Gibson ES335. Would this be first time of Gibson's history in print and how much would this book be worth to collector, I am not selling. The book sates Stradivarius violin (which had nickname) in 1974 was 300 years old and worth £84,000. The highest price paid for Stradivarius violin is $16 million (£9.5 million). Does somebody have Gibson in attic that they can retire with.
