This photo of US General Ulysses S. Grant became historically important. The brave general is shown in front of his troops, sitting on a horse with a heroic look during the American Civil War.
But many years later researchers from the Library of Congress found out that this photo had been made from 3 different photos: a photo of Major General Alexander M. Cook (the horse and the body were taken from there), a different photo of General Grant (only his head was taken) and a background image of prisoners captured during a battle (the background was taken). Nobody knows how and for what purpose this “photoshopping” was done, but all the 3 photos are real and they have all been found.
