Adam's Nest'sBlack Triangle Pin.
While "the pink triangle went on to be reclaimed as a gay pride symbol in the 1970s, helping to make this history more known. But less known is the black triangle, which lesbians wore.
The black triangle was for “asocial” individuals which included many types of people including people with mental health issues, people living with addiction, sex workers, beggars, homeless people, pacifists… and lesbians or other “asocial” women. Though the black triangle was also reclaimed as a lesbian pride symbol, there are few records of any lesbians being persecuted solely for their sexuality. Most queer women more likely suffered if they held an intersectional identity, like being Jewish, or for being outspoken political activists." Tagg Magazine
