isolating wooden helmet

A black and white photograph, apparently from the early 20th century, showing a person sitting at a desk writing, wearing a large padded helmet that completely encases their head. The helmet has small goggles over the eyes and a breathing apparatus over the mouth, connected by a tube to a gas cylinder on the left. A desk clock, telephone, and other office items are visible on the desk.
