It would seem that you can bump into this ghost picture on the web at several ghost sites. We're not sure of its story, but here's the submission information that came with what we call the 'Granny in the Door' ghost picture:
"This picture was taken by the husband of the woman in the picture on a sunny afternoon with ordinary print film. They had just moved into their new home in Chicago, Illinois. The window to the left of them clearly shows an older woman with her hair put up in a bun and a bulldog next to her. There was no one in the house when the picture was taken."
We agree that this head looks like a granny with a bulldog sitting beside her. The dog looks to be the right height, but why is the grandma head the same height? Is it a ghost? You decide...
