Two Scenes of Two Unidentified Union Officers and Two Soldiers of the 33rd New York Volunteer Infantry Regiment Posing With Their Horses During the Civil War

The uncropped image uniquely includes the shadow of the camera and the photographer. The far distance of the subjects from the camera makes the uncropped images not look very good when animated though.

Two scenes of two unidentified Union officers and another two soldiers of the 33rd New York Volunteer Infantry Regiment posing with what are presumably their horses in an unidentified camp during the Civil War. Attributed to Mathew Brady. Animated stereoscopic photographs.
