A rare photograph of Abraham Lincoln's first inauguration, on March 4, 1861, is offered at Sotheby's.
The person behind the camera is unknown, but it's possible that it could have been Alexander Gardner - a pioneering photojournalist who photographed Lincoln throughout his presidency.
Sotheby's believes this to be the first time a copy of this print has been offered at auction. It's valued at $20,000-30,000 ahead of an October 7 photography sale.
An exceptional signed photograph of Lincoln made $175,000 in a dedicated auction at Heritage on September 17.
