A large room heating furnace and an electrical generator are on the right. In the background, near the room's windows, a series of pipes and valves surround a large dial display. "26397-04-11-19," is printed in the lower right corner of the recto, and "Hydraulic elevator machinery," is handwritten on the verso. The photo is mounted on a linen backing.
