This CDV of an attractive, well dressed woman was most likely taken in the 1860's. She is wearing an unusual hat/bonnet with red, hand-colored flowers and tied under the chin. She is also wearing a fur collar and hand muff along with a long outer coat, not sure what it was called. Note the huge bow tied around her neck, looks very uncomfortable to me. She looks very elegant and most likely came from a well-to-do family. There is no identification on this woman.
The photographer was Samuel Clark, 539 Penn Street, over Neff's Store, Reading, PA. By Googling his name, I found several other Civil War era photographs taken by him including those some soldiers, but was unable to find any more information on the photographer himself.
