Ajusco - Picture wall light - Vintage/Antique

Here's a vintage - antique Ajusco picture light. It looks like it even has the original bulb in it as well. Maybe this was the precurser to the industrial lights the company made? Still has the company sticker on it.

I plugged it in and got it to work.

I have no idea when it was made, but is has the original cloth electric cord, and bakelite plug.
