there was too much going on. This is what inspired the American People Series." This revelation stemmed from her work being rejected by Ruth White, a gallery owner in New York. Oil paintings like For Members Only, Neighbors, Watching and Waiting, and The Civil Rights Triangle also embody these themes. In 1972, as part of a commission sponsored by the Creative Artists Public Service Program, Ringgold installed For the Women's House in the Women's Facility on Rikers Island. The large-scale mural is an anti-carceral work, composed of depictions of women in professional and civil servant roles, representing positive alternatives to incarceration. The women portrayed are inspired by extensive interviews Ringgold conducted with women inmates, and the design divides the portraits into triangular sections – referencing Kuba textiles of the Democratic Republic of the Congo. It was her first public commission and widely regarded as her first feminist work. Subsequently, the work inspired the creation of Art Without Walls, an organization that brings art to prisons. Around the opening of her show for American People, Ringgold also worked on her collection called America Black ( also called the Black Light Series, ) in which she experimented with darker colors. This was spurred by her observation that "white western art was focused around the color white and light/contrast/chiaroscuro, while African cultures, in general used darker colors and emphasized color rather than tonality to create contrast." This led her to pursue "a more affirmative black aesthetic". Her American People series concluded with larger-scale murals, such as The Flag is Bleeding, U.S. Postage Stamp Commemorating the Advent of Black Power People, and Die. These murals lent her a fresher and stronger prospective to her future artwork. Her piece, Black Light Series #10: Flag for the Moon: Die Nigger, 1969—which was created in response to the first image of the Apollo 11 moon landing—was to be purchased by the Chase Manhattan Bank, after Ringgold's work caught the attention of David Rockefeller, the chief executive of the bank. He sent a couple of representatives to buy a piece, and they realized, only after the artist suggested they actually read the text on her work, that the stars and stripes of the American flag as depicted also optically incorporated the phrase "DIE N****R". The representatives instead purchased Black Light #9: American Spectrum. In 2013, Black Light Series #10: Flag for the Moon: Die Nigger was shown in
