MANHATTAN, New York --A rare photograph of 19th-century abolitionist and Underground Railroad hero Harriet Tubman is up for sale at a New York City auction house.
Swann Galleries is offering the circa late 1860s image for sale during Thursday's auction of books, other printed materials and photos from the slavery and abolition eras.
The Tubman photo shows her seated on a chair and was taken in Auburn in central New York in 1868 or 1869.
The Maryland-born Tubman led escaped slaves to freedom before and during the Civil War. Tubman settled in Auburn after the war and is buried there.
