“My son caught this ghost on camera when we were in Savannah this past August. I really wanted to share it with someone. We believe she is either an African-American servant girl, or maybe Civil War nurse? Please let us know what you all think. I’m not sure of the building the ghost is standing by. We were walking down the street along the river and all of the shops. It was River Street, I think. I would love to know what building it is.”

What do you think of the photo? Does it show a real ghost or is there another, more logical, explanation?
