This photograph was taken on August 8th, 2010 at the Old Candler Hospital in Savannah, Georgia (during the day time). If you look in the bottom middle of the window you can see what I believe is a man in a black veil, holding a cane or stick tapping at the window (on the left side of the body). The other hand is holding something white, but I can't make out what it is.
The second photograph is the same window, but nothing's there.
A little history of the Candler Hospital is that it was Georgia's first hospital. It saw many casualties as a result of yellow fever and the bodies were buried in a tunnel underneath the hospital.
