This is the telephone message that was waiting for my grandfather at the New York City hotel he was staying at the night I was born. His mother (my great grandmother) had called and left the message. After my grandfather died, I found the notice in his Bible. He had kept it for all those years.
And I’m really happy he did.
Agnostic, Maybe 
Sadly, I don’t know that an email with the same information would be kept today, to delight future generations. How much are we losing? On the other hand, I’m really glad it was there for you. What a wonderful memento!
What a lovely memento. Happy birthday again!
