I like this photo for 3 reasons. First, we're pretty sure this is from the 1890s, and you don't see very many women with bare arms in he 1890s. Second, her profile is reflected in a mirror, and that is pretty neat. I've seen this before, but I'm pretty sure it's the only one I have. And 3rd, she has a very low cut neck line, in a era when most women had collars that went up to their chin.
In fact, she's showing a lot of skin at a time when usually all you saw skin wise of a woman (or a man, for that matter), was their hands and face.
I have another photo of this woman in the same dress, same necklace and everything, but in a more traditional pose.
The photo was taken by Garrison Bros. of Fort Dodge, Iowa. The Garrison brothers were Charles F. and Fred, and they had a studio in Fort Dodge in the 1890s - at least until 1896. So this photo is 116-120 years old, give or take.
I have no information on the woman, it would be interesting to know who she is and how she came to have such a photograph made.
