I’m not sure what purpose this building served, but it was likely a grocery store. It also has the appearance of some mid-century post offices.

It was a store operated by the Snider family. I remember buying candy and cokes from here as a child.
Hi Jeff,
Could you happen to give more information on the row of stores on Main Street in Mitchell, GA? I am purchasing 2 of the stores and would love to know more of their history if any.
