American Horse
AKA "Mustang"
I met Neil and have a book signed by him.
Seemed to be a nice guy.
You are lucky; at some point, as I recall, it was After 1994 he refused all requests for autographs because he found that his signed items were selling for large amounts of money and that many forgeries got in circulation; any requests sent to him received a form letter in reply saying that he stopped signing.
