Stereoview of Civil War Army of the Potomac Stirring the Pot By Anthony Union

  

Measures about 3.5 x 7 inches. This is a stereoview (also known as a stereograph or stereoscope card).

It was one of the first forms of 3D photography. The images were captured with a special stereoscopic camera, which had two lenses - simulating the view of our left and right eyes. The two, nearly identical pictures were then mounted next to each other (most commonly on a piece of cardstock, glued on as photographs or printed as lithographs). The image could then be seen in three dimensions when viewed through a device known as a stereoscope, stereopticon, televiewer and/or realisticscope. Anthony's "War Views" series often derived from negatives made under Mathew Brady's umbrella, and scenes of soldiers cooking or lounging in camps became some of the most relatable, human glimpses of the Union armies.
