Here is a very unique RPPC
(REAL PHOTO POST CARD) advertising a Kewpie-like Flapper Lamp adorned with ostrich feathers.

I couldn't help but notice the plug-in.
DETAIL
It looks like it might plug into a car cigarette lighter. Do you think the novelty lamp was intended for an automobile?
(I doubt it, myself)
Hmmmm......did cars even have cigarettes lighters in the 1920s?
Sidenote:
It's not all that far-fetched.
Many years ago my great uncle had a fuzzy 'dog' in the rear window of his car. The dog's eyes blinked,
either left and right, to show which way the car was turning. (the eyes might have worked as brake lights as well)
