Do you believe in ghosts? Are you superstitious? Do you know how to walk in heels? This last question has nothing to do with the topic but I thought I'd ask.
Steven Guess has an interesting piece on this issue. Check, check it out.
On a cold day in 1959, Mrs. Mable Chinnery went with her husband to visit the grave of her beloved mother. She happened to take her new camera, and snapped photos of the gravesite. She turned around and happened to snap this photo of her husband driving up. When the film was developed, she was certain this image of a woman with thick glasses in the back was none other than Mable’s mother. This photo has been examined by experts and has been determined to be authentic.The Ghost of Boothill Cemetary, 1990s
