An ACT UP poster with the question “How many of us will be alive for Stonewall 35?”

“Stonewall” on this poster refers to the Stonewall riots, a series of demonstrations by members of the gay community against a police raid that took place on June 28, 1969, at the Stonewall Inn in New York City. These riots are considered a seminal event in the gay liberation movement in the United States.
