Here is a T&N I put together a few years ago, but remains one of my favorite comparisons. The original is Mathew Brady's panorama of Little Round Top taken just two weeks after the battle, Here we see the rocky hill just as the soldiers saw it. As was common for Brady, he included himself in the frame with back to camera leaning on a tree. Two of his assistants are sitting on the wagon. My modern view shows the camera location to be along the Wheatfield Road right where it intersects Crawford Avenue, which was just a dirt lane in 1863.
