A school bus that has been converted into a traveling exhibit about Midwest prisoners of war in Nazi Germany is making a stop in Lawrence on Sunday.

The exhibit, “Behind Barbed Wire,” is touring the Great Plains states through the fall as it explores the experiences of Midwest POWs who were imprisoned in Hitler’s Third Reich and the human context in which their experiences took place.

The exhibit, which started in March 2004, was created by TRACES, a St. Paul, Minn.-based nonprofit educational organization. Director Michael Luick-Thrams will travel with the tour.

From 1 p.m. to 4 p.m., the bus exhibit will be at the Watkins Community Museum of History, 1047 Mass.
