Leaf from Abraham Lincoln's sum book
One of the earliest examples of Abraham Lincoln's handwriting known to exist. It probably dates from 1826, when Lincoln was 17 years old. Each side of the sheet is headed "Simple Interest" and contains arithmetic problems, as well as handwriting exercises. Other leaves from the sum book are in the collections of the Indiana Historical Society, the Chicago History Museum, and the Library of Congress.
