One of my good friends has an old telegram message framed in her apartment. Its a message sent to her dad announcing that she was born (he was in the Army or something like that at the time). It's faded and full of typos but it always catches my eye.
If you're looking for a cool way to include some retro correspondence into your wedding plans, check out Telegram Stop.
You fill out the telegram information online and for just $4.70 it gets sent to the recipient anywhere in the world as an old-school telegram! I think it would be a fun way to ask "Will you be my bridesmaid?," or to say "Happy Anniversary," or maybe even just to wish the wedding couple a Bon Voyage on their honeymoon.
