Steven, Sounds like you have the original weekly special newspapers printed in 1861, not the later bound book. As I understand it, these were special editions covering the war, and NOT Leslie's weekly illustrated newspaper. I have the first 13 issues, also in varying condition. They are titled "Frank Leslie's Pictoral History of the War of 1861" (not "Illustrated" and not "Civil War".) I have been trying to find a new home for my copies, and have almost concluded that it would be best to donate them to a library. Have you had any luck with your copies, either selling or getting appraised.
Thanks Steven, or anybody else who can help place these original 1861 newspapers.
