Abraham Lincoln (in the center) at the dedication of the Soldiers' National Cemetery in Gettysburg, Pennsylvania, on November 19, 1863.
Made from the original glass plate negative at the National Archives which had lain unidentified for fifty-five years until 1952 when Josephine Cobb recognized Lincoln in the image.
To Lincoln's left is bodyguard Ward Hill Lamon. To his far left is Governor Andrew G. Curtin of Pennsylvania. The photograph is estimated to have been taken at about noontime, just after Lincoln arrived, before Edward Everett's arrival and about three hours before Lincoln gave his famous Gettysburg Address.
Library of Congress note: Photo is a reprint of a small detail of a photo showing the crowd gathered for the dedication of the Soldiers' National Cemetery in Gettysburg, Penn., where President Abraham Lincoln gave his now famous speech, the Gettysburg Address.
Lincoln is visible facing the crowd, not wearing a hat, below a flag and twigs from a small tree. Josephine Cobb first found Lincoln's face while working with a glass plate negative at the National Archives in 1952.
