Caption reads, “A modern shop front, with windows fitted with sliding sashes.” The ‘sashes’ are the front two large-paned windows facing the street (the grips are visible along the bottom edge of the window). The sash is fitted with a sash-weight to counteract the enormous weight of a sheet of glass this size. The sash slides upward to open, allowing street-side sale of groceries during times when the weather allows and closing up during inclement weather.
