 Bauman also inspected the signature of Francis Bicknell Carpenter and the date, both of which were added on top of the varnish layer.After comparing the signature to Carpenter's other paintings, the signature was deemed a forgery.After the portrait was completely restored, Bauman determined that while it had been painted in the 1860s (likely around 1864), the woman in the portrait was not Mary Todd Lincoln and the painting was not the work of Francis Bicknell Carpenter.
