Alan Yentob spends time with the artist, author and activist, following her in her New Jersey studio and in the heart of Harlem as she prepares for her show at the Serpentine Gallery in London. Ringgold painted some of the most truthful and empowering representations of African Americans during the civil rights and women's movements of the 1960s and 70s. Despite being dismissed by the art establishment, she told her story using numerous art forms, including traditional quilts which have their roots in the slave culture of the South. Ringgold re-interpreted their function to tell politically charged stories, something she has also done with her illustrated children's books.
