Just found this photo among the boxes of family photos I inherited. Here's the front:
The lady on the left is Lizzie Pinson, wife of Thomas James Pinson. I believe that the lady on the right is Ida Norton Pinson Glenn, who was Lizzie's sister-in-law. I am waiting on confirmation.
If there are any corrections, I'll let you know.
(One day later)
Confirmed. Ida Norton Pinson Glenn had a son Bennie Pinson Glenn who had a daughter Wyma Glenn. The signature I thought said "Thyma" is actually "Wyma."
So the person on the right is definitely Ida Norton Pinson Glenn.
