I just added a link to an online application for creating Western Union telegrams from the 1920's. Just the thing if you're playing Call of Cthulhu and want to add a little something extra to your game.
(Yes, I know "medicine man" isn't the correct term in modern usage, but in the 1920's it was probably the height of enlightenment.)
Update: If you're looking for a blank telegram form you'll find one over here.
