An Abraham Lincoln signed photograph was among the star lots of an auction dedicated to the 16th US president.
Heritage Auctions hosted the "Lincoln and his Times" sale in collaboration with the Railsplitter Museum of American History. It took place in Dallas on September 17.
The image is drawn from an 1862 photoshoot by Matthew Brady and is one of the rarest portraits in the series.
It realised an impressive $175,000, placing it among the most valuable signed Lincoln photographs ever sold.
Part of the lot's appeal was its cast-iron provenance.
The reverse bears an inscription by Lincoln's secretary, John Hay, which reads (sic): "I certify the Presidents signature is genuine. [signed] John Hay."
Other highlights included a letter Lincoln wrote to his first fiance, Mary Owens, on December 13, 1836.
It's sent from Vandalia, Illinois, where he was attending the opening of the state legislature, and offers a revealing insight into his depressed mind-set.
He writes: "I really cannot endure the thought of staying here ten weeks. Write back as soon as you get this, and if possible say something that will please me, for really I have not been pleased since I left you.
"This letter is so dry and stupid that I am ashamed to send it, but with my present feelings I can not do any better."
It sold for $137,5000.
