the first and third are no brainers, really nice no doubt authentic. The second one, is not as fluid, and is either a forgery, or signed late in life. Either way, I would not want it. But the first and third are classic examples.
Thank you, terrier. I agree that number 2 is definitely the most unappealing looking of the bunch. Hope I can maybe snag one of the other ones for a good price!
