probably an adoring fan/child's attempt during the period. Probably trying to copy the signatures of their heroes that they had seen emblazoned on posters, lunchboxes, and magazine photos. Autograph album was probably sold in a rubbish sale, once purchased someone sees the names John, Paul, George, and Ringo...voila Ebay!!!!
Scans of this set were sent to me 2/3 weeks ago, I told the seller these were bad, however a few days later they show up on ebay...I think there's even a bid on them....crazy !
