Tonight, New York City Gay Men’s Chorus (nycgmc) commemorates the 50th anniversary of the Stonewall uprising with a concert that marks the occasion of the first-ever #WorldPrideNYC. The chorus made their #CarnegieHall debut in 1985 and has performed more than 50 times at the Hall. Take a look at some of their concert posters over the years, courtesy of the #CHArchives.
