Russian House Eaves Ghost

What looks like a ghost, a half-body of a man, is under the second story eaves of a house in Russia. Interestingly, this couldn't have been a person on the roof of the home, so we are left with it either being a double-exposure (accidental or purposeful) or, perhaps, the phantasm of a human.

The only description about the photograph tells us the photo was taken in 1973 somewhere in the Russian (U.S.S.R.) countryside.
