Summoning Spirits

We recently spotted this piece on the Coolidge and First building in the 18b Arts District. A small black and white collage image of what appears to be a murder scene, if look closely and you can see the shape of an reclining female head! That subtle little detail completely makes this piece for us, but then its sorta pushed too far over the top with a incomplete black fill-in, red drips and text spelling out Invoke!... It kinda reminds of us some old high school satanic stoner graffiti or something, kinda interesting!
