CSA 11-AD, 10¢ blue tied unidentified red circular datestamp on small lady’s cover with ACG embossed on flap tip, addressed to Rev. Joseph Bardwell, Chaplain Ford’s Reg’t Cav(alry) State Troops, Canton, Mississippi. $90.

Joseph Bardwell (1828-1893) was a Presbyterian clergyman. His second wife was Annie Eiza Gillespie and the cover is likely from her. All those by the name of Bardwell in Civil War Database (quite a few) appear to be from Mississippi but for two.
