Here is how the eBay listing for the photo reads.
“Original c.1870 carte de visite showing a man who looks exactly like Nick Cage. Personally, I believe it’s him and that he is some sort of walking undead / vampire, et cetera, who quickens / reinvents himself once every 75 years or so. 150 years from now, he might be a politician, the leader of a cult, or a talk show host.
This is not a trick photo of any kind and has not been manipulated in Photoshop or any other graphics program. It’s an original photo of a man who lived in Bristol, TN sometime around the Civil War.
I’ve had a lot of questions asking where I purchased this. As followers of my website know, I collect antique memorial photography — images of dead people — from the 1800s. This photo was found in the very back of album that contained an unusual number of Civil War era death portraits (which is why I purchased it). All of the other people in the album, living and dead, were identified by name — this man was not.
Photographer is Professor G.B. Smith. A contact of mine forwarded this interesting article (link) about the photographer, Smith. Turns out he was a confederate Civil War prisoner of war photographer.
Guaranteed to be an original 1860s-70s photograph and not a modern reproduction, copy or photo manipulation.”
