Hi, I'd be interested on your views on these three sets. I my view set 2 stands a decent chance, set 1 seems to be from the same hand and set 3 seems atypical in all four cases.
Just found a seller in US and I really ask me if it's not possible to stop such fakeseller: http://kenneth.flyingcart.com/
All sigs of Beatles and solo are terrible fakes. Don't think that any of his autographs is genuine.
