I've seen different Beatles signatures signed under different circumstances...did Lennon sign his name while holding the paper using his hand as a backing...or did he sign while sitting at a table??? The sigs would have looked different!!!
I agree Jim, there could be any number of things that could affect his style. At this point, I would defer to the experts such as Caiazzo or Tracks UK... it’s very close IMO but some concerning inconsistencies... I hope it’s real !
