Perry Cox had this one -- I've never seen another Lennon album of any kind signed in 1980 (except a few Double Fantasy's). Anybody ever seen another Lennon signed Mystery Tour LP from any year?
Conversation is almost 3 years old but this might be the same one from Tracks. Also certified by Perry Cox and Frank Caiazzo. So a high probability it's authentic. Value hard to say since Beatles albums signed by John from 1980 are so rare. $8000-10,000?
If this item was actually authenticated by so many learned authorities it would take a brave man to say it was a fake but to me everything, apart perhaps for the date, looks a bit too carefully drafted. The sketch and date also seem rather large in proportion to the signature.
Amazing how a thread can have no responses for three years and suddenly get discovered again - gives us all hope.
