Filmmaker Peter Kunhardt examines how a one-of-a-kind collection of Abraham Lincoln photos and memorabilia have profoundly shaped the lives and sensibilities of five generations of his family. In the years following the Civil War, Kunhardt's ancestors collected photos that might have been lost forever, including now-iconic portraits used on the penny, the 5-dollar bill, and even the image of Lincoln used for Mount Rushmore. This film profiles several key family members whose stewardship of the Lincoln collection became an obsession.
