In May 1989, Keith Haring created a mural called “Once Upon a Time” in the bathroom of the The Center as part of its “Center Show” that celebrated the anniversary of the Stonewall Riots. It was his last major work before his death at 31 years old, from AIDS-related complications, and explores the heyday of gay cruising and bathroom sex before the AIDS crisis. As Keith Haring’s work have sold for millions of dollars, it is very possibly the most valuable bathroom in America.
