Considering the photograph is furnished by a close relative of SarahStanton, it is of course beyond doubt that it represents SarahStanton. I noticed in the interview that a slight reference indicated some weight gain and/or loss over time. And, it does appear as though SarahStantonImage is older than age 40-42. Estimates tend to have variables, especially considering either way the photograph has to be at least 40 years old.
The ScarfLadyImage may appear to be holding a larger light colored purse, but my take is her purse is smaller, possibly black, and strapped to her forearm. A reference was made in the interview SarahStanton"s daughter inlaw and grand daughter, regarding MsStanton's preferred purse size. The abnormality is, I believe, a reflection of a male image standing next to the glass wall, possibly a construction worker, and wearing a hardhat.
