WPA Dioramas, 1939-1941. During the late 1930s, federal Work Projects Administration (WPA) launched numerous federal work-relief programs. One of these was the Kansas Museum Project. It created dioramas for use in public schools. Their purpose was educational; and the scenes were intended to be a realistic depiction of an aspect of Kansas history. Portrayed were episodes from Kansas history and the life of early Indian tribes. Side view of Kansas History Diorama No. 2, Four Horses Trading Post
