I found this piece in an estate sale, and it caught my eye. I'm not sure what type of photograph it is, but it definitely appears to be from the period. It measures 7.75" x 9.75". Overall it's got a great color and the image in compelling. On the back of the photo "James Campbell" is written in pencil.
