So I was serious when I said to send postcards to the Chicago Postcard Museum Don't believe me? Well, this is a scan of the card that I sent to them last week. It's a vintage Russian postal card which was blank on the back; so I drew in our logo with a ball point pen. Remember that it costs $0.27 cents now to send a postcard. Fortunately, I sent this card before the increase. I don't know where I would have been able to fit another stamp! You can see more cards that the museum has received here.
