Hopkins, Columbus, Georgia; top back flap missing, significant restoration at top, 2007 CSA certificate issued before restoration, but confirms the genuine use. Rare use that could easily be turned back at lower left corner to show the inside for display. The soldiers named D. W. Hopkins listed in military records were not from Georgia. Needs more research.
