Quarter plate full standing portrait of a Federal soldier in uniform, holding his ornate percussion half stock "Kentucky" style civilian rifle upright by the barrel. (Light blemishes to upper left corner of image, spotting to mat; unsealed.) Housed in a full pressed paper case (surface wear, loss, soiling discoloration and wear to velvet pad). 

It is possible this subject was a member of Birge's Western Sharpshooters, later the 66th Illinois. Many of them carried civilian rifles by Dimick of St. Louis early in the war.
