I should add:
My name is embossed on the front of my Allan PM1. That's not having my Bible autographed.
When my son was very young, I bought him a Bible and wrote a message on the front page of it and signed it. That's not an "autographed Bible" either.
Like many things, "I know it when I see it." Giving my Bible to somebody and asking them to scribble on it for me just isn't gonna happen.
