My friend gave me this back in the 70's. He says it was signed by Joe D way before that. It seems a bit different than the ones Joe started signing when he was selling his autograph. First of it is in ballpoint, the 'Di' appears and it is on an old sepia tone photo above a printed signature. Opinion on this?
Don't normally see the e in joe look like a e as exampled in the top signature, Also as terrior noted the o being key. The bottom Sig would be his Authentic Graph and the top being the secretarial.
