a rare thing to see, 1930s educational dioramas, 

per the ebay listing; 

 "This auction is for a Rare 1930’s WPA Museum Extension Project Diorama-Menomini Jerking Meat. During the Great Depression of the 1930’s, President Franklin D. Roosevelt enacted the “New Deal Program” creating government jobs to give the people a way to earn money and have meaningful employment.  One of the programs was the WPA (Works Progress Administration) which was a Pennsylvania state based program.   The Pennsylvania Museum Extension Project employed thousands of artists and artisans to create visual aids for use in the classrooms.  The works included costume plates, prints, puppets, lantern slides, architectural models, dioramas, puzzles, maps to mention a few.  The Museum Extension Project produced a series of eighteen small scale dioramas illustrating domestic life, customs and activates of Native Americans.   The Menomini Diorama (No. 14) is one of these models set against a painted background inside a wooden box designed with a hinged top that opens, allowing natural light to illuminate the diorama. The front window and inner roof of the box are glass.  The inner glass has one corner cut out to accommodate a wooden prop that holds the lid up.  The figures inside are created from plaster and can be easily damaged with improper handling.  The figures in this diorama are undamaged, bright and colorful.  The background is a curved piece of paper board that is painted to create the panoramic setting for the village scene.  The wooden box measures approximately 13” by 10” by 9” in height.  The interior is in great condition.  The painted black box is also in good condition.  The label has some damage.  Please review the photographs to help confirm the condition.  This is one of three WPA dioramas that I will be listing in the future.  I am also listing other items, so be sure to check back for new additions.  (#26918)"
