Covid-19 shut down the New York theater over a year ago, on March 12, 2020. #WhoAmIMaskChallenge celebrates the actors, dancers, musicians, writers, directors, composers, ushers, dressers and box office workers whose livelihoods remain on hold until it's safe for audiences to return to the theater. We applaud them for speaking out to demonstrate the power of  individual voices coming together in a crisis.
