My dad told me it was Edison when he gave me this from my Grandmother’s house in 1991.
It wasn’t Edison, it turns out to be a picture of Charles Dickens. I have no idea why my Grandparents had it or how they came across it. I don’t know how old it is or where it was taken, or what type of early photography it might be.
But Charles Dickens has been on my office wall forever and has kept me company. Sorry my Dad thought you were Thomas Edison.
