When the Coopers moved into their new house in Texas sometime in the 1950s, they took a family photo in the dining room to mark the occasion.
When the picture was developed, a chilling image turned up in the left of the frame: what appears to be a floating body falling through the ceiling.
This picture has caused a stir online in recent years, with many conspiracy theorists claiming it could be the ghost of one of the house's previous occupants.
The photo's origin is murky. There's no record of it existing prior to 2013, when it was first posted online, although it obviously looks older than that.
The presence of symmetrical vignetting in the corners has led some to believe it's a fabrication, knocked up on Photoshop, but nobody has ever taken credit for it.
