This is a very fine genuine antique Holophane bell-shaped lamp shade.
It is marked with the 1909 Patent Number around the neck section - as well as the word HOLOPHANE.
It is made of clear glass with close decorative ribbing all over - as photographed.
There are no chips or cracks.
This is a single shade - which will look great hung in any room of your house - it is simply beautiful classic design.
It comes with a later brass shade holder - which is nice and shiny - in perfect condition.
Dimensions: overall height with brass fitment is 4 3/4 inches. The diameter is 5 3/4 inches at its widest.
