Post Card UX27 Die Variety ?
I have a U.S. Post card Scott UX27 that has a line behind thew queue of Jefferson that i have never seen on any other UX27. Is this some type of die variety or just a minor printing anomaly? Could it just be an uninked area?

In those days it was common that a lot of large particles would float around in the air like bits of harvested plants. Most likely, something like that just landed on the card while it was being printed. Then blew away later, or fell off as soon as the card was vertical.
