1970s Autograph Book Containing 180+ Opera, Film & TV Signatures/Autographs

A wonferful autograph book containing 180+ mainly Opera and musicians signatures who attended The Edinburgh Festival, Royal Opera House London and other mainstream Opera houses in the UK. But there is also a Frankie Howard and Peter Ustinov. All signatures are back to back. There also seems to be a lot of no UK tenors and musicians. Sadly this area isnt something I knowledgable in. It really needs proper research.
