The contemporary Chicano mural scene seems to have started in Tucson in the mid-1970s as a part of the spreading Chicano movement of the American West and Southwest. Many murals are created with community input, often with actual painting tasks being shared by neighborhood youth as well. Tucson's mural scene is incredibly dynamic.
Murals appear, are painted over, and then are replaced by others.
The Tucson-Pima Arts Council published a Guide to Murals in Tucson in 1993. It is 20 pages long, and lists 135 separate murals. One of the murals in this exhibit no longer exists, another has faded almost beyond recognition since it was painted. But Chicano murals as a genre seem destined to be a part of this particular urban scene for a long time to come.
