Rimmed miner's helmet similar to World War I-era US Army military helmets. The helmet has a kerosene lamp fixture attached to the front. It was worn by Adam Shapic ca. 1910–1930s. Shapic immigrated to Minnesota from Croatia in 1910 and wore this helmet in iron mines near Virginia, Minnesota, until he was injured in a mining accident that left him paralyzed. The helmet was manufactured by Mine Safety Appliances Company in Pennsylvania.
