I am sorry but did not know what part of the forum to put it in.....so have not yet attached a scan but I have a card with the 4 Beatles autographs on it (but not sure it is authentic ).
My late husband collected a large amount of Beatles items from notebooks to lunch pail to dolls, even John Lennons coffee table....We had on our wall in a matted frame the album cover "Meet the Beatles' and within the same frame the card was placed and on the outer of the frame a brass plaque stating 1964.
My husband 'normally' purchased things from highly reputable sources such as Christies or Sotheby's but I can't verify that he did in this case as within the frame there is no statement of authenticity etc. Did open it and remove the items to see.
The signatures appear to be in pencil....or something similar to that and the card is rather yellowed. I sent them to see if someone in UK would be interested in a purchase and they thought they are not authentic however my late husband was just such a stickler on not having fake items it is hard to believe, though....he may have been duped himself.
Going to attach a scan in the frame....I realize noone can say for 100% sure but perhaps someone will know something, I did contact the guy who does the most of these authentications but he is not taking any new work. I did find one set of signatures online that are authentic from 1964 that have some of the same styles as these, including the 'point' of ink or pencil in the L in Paul's signature being in the exact right place.
In any case even if these are not real I have a lot of Beatles memorabilia we want to sell that is for sure authentic, thanks for any hints on these signatures .
I also have a letter from Yoko to John but this is on their letterhead so much more chance of authenticity
