New to My Collection: A Civil War Photographer

Curious to know what the men who documented the Civil War in photos looked like? Here is one of those early photographic pioneers. His identity is unknown, but two clues may put a name to his face. The back mark on this image credits the photographer as Jos. Longaker of Attica, Indiana. This may be his self portrait. The individual may also be Charley Haller. According to his great-great niece, Susan McKenney of Guntersville, Ala., Haller was a photographer in Attica during the Civil War period and owned this image.

If you have any information about Haller or Longaker, please be in touch.
