This is described as “an exhibit remembering the prophetic insights and personal courage of World War I peace protesters.” The exhibit was organized and is available for traveling through the Kauffman Museum at Bethel College in North Newton, Kansas.
The exhibit was available this past weekend at the Muted Voices conference at the National World War I Museum and Memorial. After a short stay at the Rainbow Mennonite Church in Kansas City, it will be back at the Kauffman Museum from October 31 until January 21, 2018. It is well worth a look.
