The snapshot on the right is a plaster mold of Abraham Lincoln's face currently on display at the Chicago History Museum. This, together with another mask, is currently being used by scientist to verify the claim that the 16th President of America had a facial defect called cranial facial microsomia.

Prior to all these, historians have long noted before that Lincoln's political rivals have always mocked his face. Even Mount Rushmore sculptor Gutzon Borglum commented that the president's face was primitive, immature, and unfinished. Head of the above mentioned study Dr. Ronald Fishman added:

Lincoln's contemporaries noted his left eye at times drifted upward independently of his right eye, a condition now termed strabismus. Lincoln's smaller left eye socket may have displaced a muscle controlling vertical movement. Lincoln noticed double vision only occasionally and it did not bother him a great deal.

Fishman also said that Lincoln was actually kicked to the face by a horse when he was a boy. This very incident is puzzling their team because they can not ascertain if the face defect was caused by the horse or was a developmental one.
