Library of Congress says: Portrait of President Abraham Lincoln, half-length, seated; ca. 1863. [“A crafty and determined president photographed by Lewis E. Walker, Washington, D.C., about 1863. Observe the almost casual attire, with the unbuttoned coat and the familiar watch chain hanging from the side pocket instead of the vest. The only personal ornament worn by Lincoln in any photograph is a watch chain. This heavy chain of hair-thin braided gold was presented to him in 1863 by a California delegation.” (Source: Ostendorf, p. 160)]
Illinois Library says: A photograph made by Thomas Walker, probably in 1863. Captain O. H. Oldroyd, the proprietor of the Lincoln Museum in the house on Tenth Street in Washington where Lincoln died, stated that Mr. Walker was an amateur photographer, an employee of the Treasury Department.
