Jackhammer Street Stencil April 25, 2010 Living Saw both of these today while walking about on a warm Sunday in SF. The one on the left is down the street in SoMA near 111 Minna, and the reverse black stencil was near Ritual Roasters on 1026 Valencia Street, SF. jackhammer sf stencil streetart Older Post Touch Gesture Reference Guide Newer Post TiltShift Waikiki
