Photograph of instructional exhibit by Frank Wiggins Trade School, showing students and teacher, ca.1920-1929. At center, a small structure in an enclosed studio can be seen. Wooden beams can be seen at the top of the roof, and brick has been placed along the sides of the walls. A student stands near the doorway of the structure holding a small tool in his hand. Two bags of plaster sit on near the doorway. Another student at center mixes the plaster in a small tub, while a third student smoothes the plaster over a wall at right. A fourth student stoops down near the side of the house and spreads a thick substance over the brick wall. The teacher wearing a tie can be seen standing nearby. A small sign near the top of the building reads: "Instructional Exhibit. Building Trade Students. Frank Wiggins Trade School".
