In 1996, Ike Clanton, dressed in cowboy attire had his friend photograph him while he stood in Boothill Graveyard in the famous Tombstone, Arizona. After reviewing the photograph, Clanton noticed a man in the background of the photo that was not there when the photograph was taken.

Clanton was intrigued by this and set out to recreate the photo with a friend standing in the background and discovered it was impossible to recreate the picture without having the legs visible. This photograph remains a mystery to this day.
