The "safest" Griffith's are checks, contracts and the Britt COA's when he sold personal items in the early 1990s. Richard O. Linke did most if not all of his TTM requests. Some must have gotten by and there are the odd photos and playbills. His wife was very protective of him and very little got signed in later years. The Griffith shown is not by Linke and in my opinion Andy Griffith never saw that piece of paper. The Dodson looks good to me, but he was a pretty generous signer.
