Appears to be Cooper, Eltie inscribed on the photo. The photo is quite old - no date written on the picture but the actual photo appears to be done on some sort of "plastic" or resin.
Photo found in the collection of Martha Sigler Ross of Brush Creek Twp., Muskingum Co OH while we were working on the Ross - Sigler - Barringer family history.
Do you recognize her? Please let me know.
