The Museum of Modern Art in New York has just acquired the original rainbow flag, designed by artist Gilbert Baker.
Back in 1978, Baker used the sewing skills he developed as a local drag queen—and the help of 30 volunteers—to make the first two rainbow flags, which were hung at the Gay Community Center in San Francisco.
Here’s a breakdown of what each color represents. (The flags original design included hot pink, to represent sexuality, but Baker ran out of dye so it was nixed.)
