Which George is the original, which is the copy? Or are they both forgeries? The EP is on eBay. The Miami card has been discussed previously on this board for its similarity to other disputed sets in the past.
My eyes tells me that the George signature on the post card is the same signature that is on the rear EP cover. It looks to have been cleverly re- printed onto the record cover. The N part of Harrison was printed over the TH of the record cover. IMO, The postcard signatures look to be signed in real ink and the record signatures appear to be totally different and not signed in real ink.. If the consensus is that the post card signatures are fake then i guess both George signatures are fake.
It appears to be the exact same signature to me too. I agree with spaceman that it looks like the Harrison signature was reproduced onto the EP. I’m going to try to find the Lennon signature.
