While this may be of little consequence to the average American, history lovers like myself eat this kind of stuff up. While Roosevelt and Lincoln were both presidents, a fascinating photo shows another link between the two -- a future president observing the passing of another.

This picture (via IBD) shows President Abraham Lincoln's funeral procession along New York City's Broadway on April 25, 1865 -- 10 days after his assassination at Ford's Theater in Washington, DC. The photo also shows a couple of young boys perched in a second-story window watching history unfold. Those boys were Elliott and Theodore Roosevelt. At the time, Teddy would've been only 7-years-old.

As a child, Roosevelt watched as Lincoln's assassination brought the country to a stand-still in 1865. Thirty-six years later, Roosevelt became America's 26th president after William McKinley succumbed to infection following an assassination attempt.
