Newcastle autographs

One lucky fan got to meet the lads backstage in Newcastle.   That poster that came inside of the Beatles' show program is what was autographed by them and it went up for auction a while back.  Below is what the seller had to say to authenticate the signatures:

“I confirm that on Saturday 4th December 1965 I had a ticket for the Beatles show at Newcastle City Hall. My dad’s uncle by marriage, Bob King, was at the time working for Arthur Howes. My grandma gave him my ticket number and he took me backstage to meet the Beatles. They signed the autographs in front of me while watching television.”
