From Thinkwalks:
For this free Thinkwalks event, Joel will be hanging out at the corner of Valencia Street and Clarion Alley bringing it to the people. He’ll make a series of short presentations covering various topics like Coit Tower murals, the “Mission School” of muraling, Ohlone murals in the Mission Dolores, Clarion and Balmy Alley murals, and muralists from Diego Rivera and the Stackpoles to those working today. The event will offer passersby a series of short presentations each followed by question-answer and a ritual passing of the hat.
