Victorian Photo Image

I have recently acquired a large oval portrait of a Victorian mother from the back with her frock pulled down over her shoulder seeming to nurse her baby. It is a very beautiful image and I couldn't pass it up because I felt it was quite unusual. It does a have a bit of water damage and it has a date of 1901. Has anyone ever seen such a thing? Have any idea of its value?

Can you post a picture or two, and give some more information about its size and details. Is it in a frame? Do you see any identifiers on the front or back of the picture, or on the frame?
