What meusems has cleo mussis art featured in?

It seems like you're asking about museums that feature the art of "Cleo Mussis". However, there's no widely recognized artist with that name. It's possible there's a typo or you're thinking of an artist with a slightly different name.

To help me find the right information, could you please double-check the spelling of the artist's name? Or perhaps you could provide any additional details you know about them, like their nationality, style of art, or any specific artworks they are known for?

With more information, I can hopefully help you find the museums that feature their work.
