a mural by Cristina Cárdenas at 29th & 4th in South Tucson. She also told me about another mural of hers in a place I wouldn't have thought to look: the Minimum Security Facility on South Mission Road. Although it's too bad that people inside the prison can't see the mural, it sure brightens the view from outside! A sign on the fence warned me to stay 20 feet away from it, so a photo had to show the fence.
Here's a closeup (which, as always, you can click on to get an even larger view):
