I picked up this image recently at an antique show in Jackson, Mississippi. It is not identified, but all of the soldiers in this World War I era image are armed with shotguns.
You did WELL..Thanks,
I paid all of 10.00 for it, so I was a happy camper. I picked up another image taken at the same exact location as this one showing a group of civilians, so it must have been some kind of patriotic observance - I wish they were identified!
