The back says:
M.J. Parker Adams
Mrs. F.S. Adams
I'm going to assume Mrs. F.S. Adams is the subject of this portrait. (If so, who are Edna and Auntie M.J.?) She is wearing a dress with large leg o' mutton sleeves that became popular in the mid-1890's into the late 1900's.
This doesn't exactly fit with this weeks prompt, but I thought I'd share it anyway!
