Literary signs

Three unidentified white women that are part of the Phoenix Books' group (either before or after the 1992 Kansas City pride parade) in a park with triangle shaped signs featuring drawings of open books with a title and author; first sign reads "A letter to Harvey Milk, Leslea Newman" the second "Another mother tongue, Judy Grahn" with the third woman's sign turned away from the camera; other people are behind them including one person with an American flag with a pink triangle instead of stars in the blue field.
