The cover appears to be a perectly genuine legitimate Buena Vista manuscript, but the stamp has been added to the cover. On careful examination, there is a manuscript "pd 10" concealed under the stamp. The brown postmark (Holden SC) is a complete fake. There is no entry for a Holden SC on the listing of CSA post offices. Also, the postmark is not consistent with the type of marks used in the Confederacy.
