Yolanda López (b. 1942 in San Diego, CA; d. 2021 in San Francisco, CA) made Free Los Siete to bring attention to the 1969 arrest and trial of six Latino youths from the San Francisco Mission District, known as Los Siete de la Raza, who were accused of killing a local police officer. This event sparked widespread protests among Latinx communities, who experienced police targeting and abuse, and led to the founding of grassroots newspaper Basta Ya! (Enough!), where the poster was published.
