A Very Old Phototgraph

Photography is 188 years old.  In 1827, Nicephore Niepce, an amateur inventor from France, came up with a photographic process that used a bitumen coated tin sheet to create a permanently fixed, direct positive image.  It can be seen on my Fair Use blog.  My guess is that this photo is around 150 years old.  It's printed on paper, and was probably printed from a glass negative.  If I'm right about the age of this photo, when I was born, in 1955, there were still a handful of people alive when this picture was taken.  When my father was born, in 1919, there were a handful of people still alive when that first photo was made.  All things considered, a very old photograph isn't all that old.
