Photograph of a man working in a Shell Oil Company refinery, ca.1940. What appears to be a small telescope hangs from the thick drill at center while a man leans from the left to look into the eyepiece. The man in stained coveralls and a hard hat balances along the edge of a circular platform which surrounds the hole where the drill penetrates the earth. A short, oil-stained wall inclines to behind the man on the left from the opposite side of the platform on the right. The wooden frame of a room of the refinery stands in the background behind the man and the wall.
