This postcard was available at the hotel so visitors could tell friends where they were (and thus, no doubt, advertise the hotel).
Roberta Watts Cook identified the occasion as being the wedding of her aunt Nannie Will Overstreet to William Thomas Smith on 1 May 1907.
If you look carefully, you can see the wedding couple arriving by horse-drawn carriage at the right side of the photo.
Like most buildings in the area, the hotel had no cellar; to compensate for the slope of the land, the floor was supported on stone and brick pillars visible under the veranda.
The original photo was black and white; this postcard version has been hand-tinted.
A cropped high-resolution image of this scene is available at the University of Georgia site.
Controls at the bottom of that page allow you to zoom and pan the image to look at fine details.
Can you identify any of the 22 people pictured?
