Spotted yesterday on Mariposa Street, just up from Harrison: a van mural depicting, among other things, the famous 1962 escape (or possible escape) from Alcatraz. I love the three happy-looking stick men in the raft and the figure of the guard in the background. Also the legend, “Stay Free Yo.” It looks like local taggers have been adding their bit to the art. Also visible here: allusions to the Golden Gate Bridge 75th anniversary earlier this year and occasional forays into the bay by passing whales.
