When I receive a new-to-me photograph, I scan both the front and the back of the photograph.
Many times, there is identifying information written on the reverse side. By scanning, both the information and the handwriting of the “recorder” are both preserved.
This photograph is especially touching to me as this is a photo of my grandfather. For many years, my mother’s family – all of us along with her parents and her brother’s and sister’s families, met in South Carolina for the 4th of July.
