I found this interesting

150 Year Old Photos......If you are a history buff these will be interesting to you. THESE PICTURES ARE VERY PROFOUND It is fortunate that these have survived. Most probably a million wet plate photos were made during the civil war on glass plate. Popular during the war, they later lost their appeal and many were sold for the glass. Many used in green houses. Over the years the sun caused the images to disappear. These are pretty amazing considering they were taken up to 150 years ago: A collection of photos from the era of the War Between the States. Run the cursor over the photograph and the picture caption will pop up. Click on the photo to enlarge and to read the story. Click Here Please
