Sorry, I don’t own the book and I have no plans to purchase it.
So you only “supposedly” believe that there are photos of the birth certificate in the book?
And neither do I. It's doubtful if it's obtainable in Australia anyway. But your reply does make me wonder, are you an American?
Have you actually seen the object you described in your comment? You mentioned the front and back covers. What about the important middle where one might find the names and dates etc...? Was that shown in the book?
