Clarence,

This could be a United Daughters of the Confederacy flag or even a United Confederate Veterans or Sons of Confederate Veterans flag. These came into existence in the late 1800s and into the mid-1900s typically. These were made to look like real flags where possible. That is how there is a letter from the 1940s about repairing your flag.

The flag in Atlanta is THE flag of the 5th Georgia from 1864. Please read the article that I sent you about it.
