Bear & Skull

Here's a new piece of street art in SOMA on 12th betwixt Folsom and South Van Ness/Howard. I like it. Not sure if the piece is in reference to the Bear culture that prevails in the SOMA area, but beyond all that, it's a nice piece. This bear sits comfortably, cross-legged and civilized atop a death skull, and just to expand upon the visual metaphor; the death skull sits comfortably atop a flying death skeleton. Why not, Bear & Skull? Welcome to the neighborhood.    

UPDATE: It seems this is a piece by Ryan Travis Christian (RTC).
