This granite capital was from a 19th century building that has been torn down. Nobody remembers what building it came from. It sits in the grass at the NE corner of the Old Courthouse Museum in Sioux Falls, SD.
When I photographed it with my iPhone, I almost forgot to include the wallet scale card so I could make it real world measurable. Since I included the card on just the last few photos, it shows up as a ghost. Whoops!
