CSA 11, 10¢ blue (3 margins, tied by blue COLUMBIA S.C., JAN 12 cds to Col. W.C. Butler (later General), Chappells Depot (Michlans Mail - ?) S.C. on Southern Mutual Life Insurance Company, Columbian, S.C., fancy scrolled corner card with original matching letterhead See letterhead page 1 and page 2 (the blue underlined links) dated Dec. 27, 1864, and additional letterhead certificate, shown with the cover. Very Fine.  The "Michlan's Mail" - if that is how it should read - is a conundrum. Presumably this is a private carrier, but I could find no information on it. It is a worthy project for the ambitious postal historian. $275.
