This large, vivid mural in the Garfield district, a historic area in downtown Phoenix, is 6 feet tall by 95 feet long. Its actual title is Knowledge Breaks Down Barriers Created by Ignorance and is the work of Raul Gonzalez, an L.A. based artist, and many youth of the Garfield District. A community activist states, “The mural was designed and created by youth and depicts what is important to them, which includes family, culture, justice, and education.”
