Unsigned original 2.5 x 4 carte-de-visite bust portrait of Lincoln, by an anonymous studio. In very good condition, with scattered foxing and soiling, and clipped corners. The original photograph was taken by Henry F. Warren on the White House balcony on March 6, 1865, just a month before Lincoln’s assassination. While there has been some disagreement about which is the last photo ever taken of Lincoln, this image has recently emerged as the consensus choice among scholars and historians. RRAuction COA.
