Vintage square glass ceiling

Glass ceiling circa 1960. Beautiful shapes and ripples of glass. Bubbles are present in the glass. Some traces of oxidation on the metal support (specifically the edges). Electricity tested, requires a bayonet bulb. Weight 1.3kg I try to describe in all the best and honesty the peculiarities (negative or positive) of this object, however do not hesitate to contact me if you wish for further details or photos that I could have o'atpassed; I would be happy to respond as soon as possible.
