Anna Botsford Comstock Photo

I found this picture of Anna Comstock this weekend. The person that sold it to me told me who it was and said her father knew her (or grandfather not sure) She said the picture came from NY how he ended up with it I"m not sure. It has the original backing on it with a Photographer sticker from NY in the order space "Mrs Comstock" It's sweet as I can not find this picture of her anywhere making me think it's from a private owner.
