George Wunderlich, director of the National Museum of Civil War Medicine, poses for a portrait with a replica of a Rucker ambulance at the Pry House Field Hospital Museum Friday, June 21, 2013, in Keedysville, MD. The house is located on the Antietam Battlefield, which served both as Union General George McClellan's and Union Army Maj. Dr. Jonathan Letterman's headquarters during the battle.
