I love this old photo postcard. It shows John W. Snook, Warden, and D.W. Ackley, Assistant Warden. Another gentlemen is identified as the "florist" but not named. May be a prison Trusty.
About all that remains of the hospital is the foundation. It was damaged/destroyed in the 1971 riots at before the old pen was closed down. Deputy Warden Ackley was a familiar figure during the 1907 Haywood trial. He was a Prison Guard at the time and one of Orchard's escorts to and from the Pen & Courthouse.
