This summer I've read a handful of books about the American Civil War and I just finished Cold Mountain by Charles Frazier. In it, the main characters Ada and Inman exchange tintype photographs of each other before he goes off to fight. In these early days of photography it was a big deal to have your photograph made, and to have a sweetheart to entrust it to. I was curious about what these looked like and there are plenty to browse on the web. Being on metal, I guess it makes sense that these images survived the years.
