Is it culturally insensitive to hang and display northwest coast indigenous masks?

I have always loved the art created by Haida, Salish, ect artists. In particular, I love the intricately carved masks and have been considering purchasing a raven mask for my apartment. However, when I was younger I was taught that display some items like drums is frowned upon. Does this carry over to masks? I would not be purchasing something previously used in a ceremonial capacity (not used the feast or dances). Does this affect the taboo against display if there is one?
