Grave Marker

I am always looking and researching for items that are odd but with a historical significance. This marker is in a museum in SD and it struck me. So this museum claims these markers were used around the Black Hills region and Custer Battle Field. Anyways I had to make one ! Needless to say it was hair raising to event to take a picture. I found some thick sage overgrowth in the desert and snapped this picture. I believe that a historical society had these made in the 1890's..
