The picture that I think that fits role #4 is by Faith Ringgold "God Bless America". Faith Ringgold was born on October 8, 1930 in Harlem and she started painting 35 years ago. She has been painting for 35 years and is now best known for her quilts and storytelling. This painting was made during the Civil Rights Movement and had to do with the prejudice towards the African Americans. The picture had to do with the struggles that her community were facing while trying to gain equal rights. The women is portrayed as a racist denying African American the right to vote and is a prisoner to her own bigotry. As you can tell that she only uses red, white, and blue colors in the picture. She also uses a star which is meant to be a sheriff's badge and the rectangles are meant to be jail bars. She has exhibits in major museums all around the world.  Ringgold is not just a painter but she also is a a witter. Her very first book she wrote was Tar Beach which won a lot of honors. She has received more than 75 awards, fellowships, citations and honors. 
Here are some of her books:
