This vintage 1940s - 1950s light shade is for a flush mount ceiling light fixture. It's 8 inches high by 4-1/2" wide at the center. The fitter opening is 4 inches diameter exactly. The white frosted body has a curved hourglass shape with bands of clear vertically ribbed glass above and below, ending in a clear glass flat bottom dome with diamond point texture and bullseye rings in the center to spread light. In excellent vintage condition with no damage or scratches.
