Scary Wedding Day Ghost Picture

Every once in a while we receive an old ghost picture we've seen before on the Internet. What's the story behind it? Do you have additional information behind the photograph below of a possible scary wedding day? If so, please write us...

"This is a picture of my aunt's wedding day, the year was 1942. The picture was taken in Jasper, Alabama with a box camera. I need some feed back, please. I give you my permission to post these pictures. Look on the front of my aunt's dress. It looks like finger marks. Then, look close behind her in the tree. What would you say this is, a ghost or demon?"

We love this ghost photograph and know it is a classic we've seen somewhere before.  Please help us identify it.  Of course, our view is that it is a wonderfully staged picture, not a real ghost.
