Photograph of the interior of the Thermador Electrical Manufacturing Company, 1953. In the center, a lightly colored rectangular box sits on a tiled floor. The box has a door on the right side and seems to have a second thick door on the left. To the right, there is a tall metallic box with a long thick door and what seems to be a ventilation system on the bottom. A darkly colored device is attached to the right while a complicated piece of machinery sits to the left. The wall behind the objects is a barren brick wall. The back of the photo reads, "3. Environmental testing equipment in laboratory".
