The scrapbook was stuffed full of snaps of A-listers.
So, who is the mystery woman?

She's actually been identified - and her story is rather cool.She's called Maria Snoeys-Lagler.

An she was actually quite a big deal in Hollywood - as her pictures prove!She was a member of the Hollywood Foreign Press Association.
