Wikipedia says: This daguerreotype is the earliest confirmed photographic image of Abraham Lincoln. It was reportedly made in 1846 by Nicholas H. Shepherd shortly after Lincoln was elected to the United States House of Representatives. Shepherd’s Daguerreotype Miniature Gallery, which he advertised in the Sangamo Journal, was located in Springfield over the drug store of J. Brookie. Shepherd also studied law at the law office of Lincoln and Herndon.

Library of Congress says: 1 photograph : quarter plate daguerreotype ; plate 4 1/4 x 3 1/4 in. This daguerreotype is the earliest-known photograph of Abraham Lincoln, taken at age 37 when he was a frontier lawyer in Springfield and Congressman-elect from Illinois. (Source: Ostendorf, p. 4)
