The image is a vintage postcard from the Coal Mining Anthracite Region of Pennsylvania. It shows two men working in a coal mine. The mine appears to be underground, as there are piles of rocks and debris scattered throughout the tunnel. The men are wearing hard hats and overalls, and one of them is holding a shovel. The other man is standing on the right side of the tunnel, looking up at the ceiling. The caption on the postcard reads "A miner testing the roof, following a blast."
