VERY FINE. A RARE AND POSSIBLY UNIQUE EXAMPLE OF A BLACK JACK STAMP USED ON A POST-WAR SOUTHERN EXPRESS COMPANY COVER FROM SOMEWHERE IN THE SOUTH TO NEW YORK CITY.
The Black Jack paid the local 2c rate for delivery in New York City, which is where this cover entered the mails. The origin is unknown, but the Southern Express Company carried mail for a period after the war, when regular postal routes in the South were still disrupted.
