Today's picture was taken in 1938, which would have been the 75th Anniversary of the Battle of Gettysburg. The picture was taken in Pennsylvania. They are flying some Battle of Gettysburg veterans over the battlefield for the 75th anniversary of the battle. The battle was in 1863, so you could imagine someone born in 1846 would have been 17 at the time of the battle, and would have been 92 at the 75th anniversary. I also understand that some soldiers could have been quiet a bit younger at the battle. But in any case, by the time the 75th anniversary rolled around, I would image the surviving soldiers would have been no more than a handfull.
Below is rare video from the reunion:
