What I've learned since the last post:
*I was able to find the photographer WGR Frayser (both Jr and Sr) in the Danville, VA directories. This photography studio was only in Danville, VA from 1888-1891. That narrowed down the age of the photo quite nicely.
*The woman's hairstyle should also have been a clue to her age. She is wearing bangs which apparently did not come into fashion until the 1880's.
*The card thickness was also another clue. I learned that the 1mm thickness placed this CDV in the 1880-1890's.
Today as I was studying this particular CDV, I decided to take another look at my collection of family photos and see if I had any other CDV's or cabinet cards by the same photographer. I found not one, but two! One of a young man and one of a young child:
Maybe a family group?
