Vintage Chevrolet GM Dealers Sign 2 sided Promotional Advertising Salesmans. The plastic 2 sided Chevrolet promotional dealers sign was made to sit on the salesmans desk. The base measures 4″ square the sign measures 12 1/4″ tall and slides into the base. I listed this as used however I think it was probably never set out. I also have Cadillac and GMC trucks that I will get listed shortly. They are all wrapped up in the same style bag. These came from a family members estate with lots of model cars and other items.
