Any guess at when the picture was taken? Clues that we have so far are the hair style, no makeup (She has beautiful and natural "Cupid's Bow" lips), no earring holes, no manicure, and the dress. She lived 1887 to 1933. Although portraits may be different, I cannot tell if a glass plate negative was used. "Modern" day nitrate film negatives were invented in 1903. And I will NEVER guess a woman's age.
