In one of the only known photos of Abraham Lincoln taken on the day of the Gettysburg Address, Lincoln can be seen seated, hatless, just below and to the right of the flag. Lincoln began developing symptoms of smallpox on the train home to Washington, DC.

Presidential Pox, 1863

Researchers continue to debate whether US President Abraham Lincoln was coming down with smallpox as he delivered his famous Gettysburg Address, and if he had been immunized.
