Shanks to Shakers is a pictorial look at the Missouri State Penitentiary. Mark Schreiber is a local historian and used to work at MSP. He has collected an impressive array of artifacts, photos and postcards from the prison. MSP was the longest continuous prison west of the Mississippi River when it closed in 2004; it opened in 1836 and was in operation for 168 years. At one time it was called the bloodiest 47 acres in America. I just took a ghost tour of the prison and found the history of the place fascinating.
