Signed 1973 Notre Dame National Championship Team Football 60+ Signatures

Description

Please see photos.  Signatures I could read all match with 1973 Team including the coaching staff, three captains of that team Dave Casper, Michael Townsend, and Frank Pomarico.  The three captains signed on the white part.  Also includes Al Hunter who would have been a freshman that year.  So not sure how it could be any other team but the 1973 team.
The ball does need some air and the signatures are in ball point pen so some are hard to read and have faded..  I do stand behind this as authentic if you can provide me proof of rejection by PSA or JSA within 45 days of purchase I will refund with return of item in same condition.  But must have proof of rejection.
I counted 60 plus signatures. Let me know of any questions or need any more close up photos.  Will ship fed ex ground or USPS.  Fed ex ground seems better right now.
