A black poster features a large pink triangle. Within the triangle, a woman wearing a jacket raises her fist into the air, and she is shouting. Above the triangle are the words “NEVER AGAIN!” Below the triangle are the wods “FIGHT BACK!” At the bottom of the poster, text reads “The pink triangle was used to identify the thousands of gay prisoners who died in concentration camps in Nazi Germany.”

Poster designed by San Francisco’s Too Much Graphics in 1978 to mobilize Californians to vote against Proposition Six (known as the Briggs Initiative), which would have banned gay and lesbian people from teaching in public schools. (GLBT Historical Society)
