It's fun, all in a day's work

Seated man in deep sea diver's outfit attended by two assistants. Caption: "It's fun, all in a day's work: Louis Grenon, diver-welder, grins at Frank Boland, who will place the 65-pound helmet on him as soon as John Entvedt checks the screws on the water-tight breastplate. Boland and Entvedt are also diver-welders at the Eagle's Navy Yard Exhibit."
