Photograph of three factory workers making beads (treads?) and working with machinery, ca.1945. At center is a woman visible from behind and above hanging a stack of thin metal hoops onto a hook. She has dark curly hair and is wearing a short sleeved checkered shirt, slacks, and white shoes. The woman is facing a man who is partially visible from the side facing left. He wears a white shirt and is working with a circular object on a machine. At left is a man visible from the front working with a machine, and is wearing jeans, a short-sleeved, collared, button-down shirt, and glasses. Rolls of what appear to be some sort of cloth are to the right and a canvas bag is visible hanging from a hook.
