The first thing to realize is that there are several styles of signature that JC has used over the years.
ABSOLUTELY guaranteed authentic ;) !!
Believe authentic. Purchased from the "in person collector".
Believe authentic, based on my experience and many examples of JC's handwriting and printing.
There is another signature that I believe is authentic, and I have several examples of it. The first I will put
up is a hand-written letter from 1985 and the other is an AFTRA contract signed in 1997. The signature is not what I
refer to as a "fan signature" but what he signed on personal letters or legal documents.
