Just found this photo on Shorpy: History in HD. According to "Shorpy", it's a Currier Photo taken in a laundry circa 1905, possibly in Boston.
The Shorpy site contains an interesting discussion about what's on the ceiling in the photo. I also notice that the woman to the right is standing on a raised wooden platform--probably because the wringing device she's operating (or the process of getting wet laundry out of the sink into the wringing area) generates spilled water on the floor--this might keep her from standing in water, or slipping. Or maybe it just makes her taller?
