rotating pole

This one doesn't refer to rotating poles in engines. From the context, I'd say it was something that people used to keep in front of their shops to draw attention, a kind of advertisment. The passage is about a place still having a look of a town from 1950's, and it says:

"Crenshaw's Barber Shop had a rotating pole out front (etc.)."

So, the question is - what's rotating pole here?

PS I tried to find pics online and the only one worth mentioning was a stiped rotating column, but of a much later date.

This is a "barber's pole," which spins to create an illusion of, well, you can read the peculiar history of it here:
