Original Civil War CDV image of two Cavalrymen

This is a great original Civil War Cavalrymen CDV. It shows two young men, one standing with his hand on the shoulder of another seated man. The standing man has an eight-button shell jacket, two buttons on each cuff, and wearing knee high boots. The seated man is wearing what appears to be an eleven-button shell jacket, three buttons on each cuff, a vest, gold watch chain, and high boots. There is no backmark.

Civil War cavalry images are always popular but having two men in one photograph is even more desirable. It appears that the card on this image has been very slightly trimmed on the top and bottom, but not the actual image. This is a unique Civil War CDV.
