  • Source states re Calhoun image: "The original print of the engraving by A.H. Ritchie of John Calhoun, circa 1852. With the help of modern reverse image search, it's easy to find information on past iterations of images like this one."
  • Source states re Lincoln image: "In one of the earliest examples of photo manipulation, the head of Abraham Lincoln is superimposed on the figure and background of an earlier print of John C. Calhoun. For almost a century, no one noticed the image was modified—until photojournalist Stefan Lorant noticed Lincoln's mole was on the wrong side of his face."
