Topic: Andy Ho - control room technician - You Only Live Twice

Has anyone got an autograph of Andy, that I can compare to mine.
I am sure it is real as it was signed in Maurer's restaurant , Soho in the 1960's.
The book was used for visitors to the restaurant and had cast members and the director of the film Zulu, that I have already sold.
I also have just found David Vaughan in there as well. He is Sadie Frost father
I purchased the book many years ago and sold a lot of the autographs but recently I revisited the book and found Andy's signature
Andy had his own restaurant in London and lived there most of his life.
I am presuming that it is a very rare signature as I can't find another anywhere on the net.
Any help would be gratefully received
