I have a autographed copy of the book "The Cobra Story" which my father had autographed by Carroll Shelby at a car show in 1965. Does anybody have an idea of what the possible value of the book could be or where I might be able to find out the value. I'm not trying to sell it as it has sentimental value to me due to my father passing away just a few years ago. He owned 2 original A/C Cobra 427's and a Viper GTS Coupe which was one of the first ones to get the "Venom" package upgrade.

I know the book may not be worth too much now, but as with any autograph, the value will sky rocket upon the death of the person.
