Killer quarter plate tintype! This came from the estate of Captain Albert A Nickerson who served with the 7th Maine Infantry and later the 1st Maine Veteran Infantry. According to the family Nickerson served with the 3rd Maine Infantry which would coincide with all of the 3rd Corps badges which are seen being worn here but I could find no instance of him serving in that regiment. Regardless the image is exceptional. Seven Federal infantryman dressed in great coats and frocks all sporting the red diamond for the 3rd Corps. It would appear to be 6 privates and one 1st sergeant. Nickerson would serve all four years of the war and be wounded while fighting at the Wilderness. I believe that may actually be Albert standing in the back row second from the left based on another view of him held at the Maryland State Library. Absolutely killer view in beautiful condition! It comes housed in a full leatherette case with a separated spine.
