Yes, we know you see 8 signatures in the photo. No, the 7 in the title is not a typo. The Sid Luckman "signature" is secretarial, the remaining 7 are authentic. They include:
Sammy Baugh deceased 2008
Otto Graham deceased 2003
Johnny Unitas deceased 2002
Bart Starr deceased 2019
Sonny Jurgensen Mbr>Ace Parker deceased 2013

Our usual authenticity guarantee applies, with the caveat that it will have to be for a full letter of authenticity. Authenticators will not do a basic certification on a multi signed item if one signature is secretarial, but they will do a letter where they can note it in there description. As usual, if you wish to take advantage of our guarantee, notify us before paying your invoice. The cost of authentication will be added to your invoice, and we will submit on your behalf. In the event it does not pass, we will refund both the purchase price and the cost of authentication.
