The image shows two men working on a large metal structure in a warehouse. The structure appears to be a conveyor belt with multiple cylindrical objects attached to it. The objects are arranged in a grid-like pattern and are secured to the structure with chains. The men are standing on either side of the structure and appear to be inspecting or inspecting them closely. The warehouse has a high ceiling with metal beams and there are various tools and equipment scattered around the floor. The image is in black and white and appears to have been taken in the early 20th century.
