Historic Original Tintype Photo Helen Keller and Anne Sullivan Tuscumbia Alabama

Vintage early 1900s tintype featuring Helen Keller and Anne Sullivan, most likely in Tuscumbia, AL. From the estate of the late Hewitt Jackson, a well known photographer and political figure in Florence, Alabama. It measures 2x3 and does have some dings, but remains a historic image of a legendary pair. Unfortunately, I do not have any additional paperwork.
