Handwriting-wise, the signatures on the 22 October 1964 bill of sale and the 22 October 1964 affidavit that Ripley's has are identical to the signature on the affidavit that was signed in front of notary public Mary Rattan on 22 November 1963.

First of all, why do you represent something I've never written as a fake quote?
Secondly, since when are you a handwriting expert?
Thirdly, you might want to compare the Mary Rattan affidavit, dated 22 November 1963, with the fake one which doesn't even identify the "notary"
But there's an easy solution; Bill could simply ask new best friend Frazier to confirm the Ripley's "affidavits" to be authentic.... so why doesn't he?
