These images below were shot at a small flea market in Dickson, TN (1907 Hwy 46 South, Dickson, TN 37055). The antique store on site is fascinating, but the flea market itself was nearly empty. The signs might be replicas. I found it odd that the five signs in one image have identical shape, despite being advertisements for different manufacturers. Maybe the signs themselves were made by the same company. The presence of red rust indicates that some are made of, or have been in contact with a ferrous metal.
