Here is what he says: "These pictures are very profound. It is fortunate that they have survived....They are pretty amazing considering they were taken up to 150 years ago."
He goes on to say that they were wet plate photos made on glass plates. After the war people lost interest and many were sold for the glass. They were often used in green houses and the sun caused the images to fade.
It will be well worth your time if you are a civil war buff like I am, to look at these heart-wrenching photos. These were shown with permission of the Library of Congress.
