The masks are from vastly different cultures, ancient and modern, some for ceremony and traditional arts, some for utility and protection, some for fun and entertainment. There’s a Pokemon Pikachu halloween mask, as well as an N95 mask worn by hospital staff (and, in the COVID Era, anybody who can get their hands on one.) See pix below.
The “Noh” in the title refers to a traditional form of Japanese minimalist, classical theatre performed since the 1300s. “Noh” actors wear masks to represent different characters throughout a performance.
