I have two of these and from everything that I have saw online I think they might be from or based on a design from the 1930's.
Does anyone have a more knowledgeable opinion?
Don't know anything about that piece. I suspect there were little clip-on shades that fit on the light bulbs, or decorative bulbs with twist tops were used.
It needs custard glass shades! Art deco/streamline 30s coolness. How do the shades attach?
