Who are some famous PINO artists?

There isn't a recognized art movement or style called "PINO." It's possible you're thinking of a different term, or perhaps you're referring to a specific group of artists or a specific region.

To help you further, could you please clarify:

* Are you thinking of a specific acronym or abbreviation for a particular art style or movement?

* Could you provide more information about the artists or their work? For example, do you know their nationalities or the time period they worked in?

* Do you have any other clues or details about "PINO" that could help me understand what you're looking for?

Once you provide more information, I'll be happy to help you identify the artists you're interested in.
