Black graffiti on a white wall. The art is drawn in one-single line and depicts a large head of a mean pitbull, with a spiked collar. It is drawn by an artist named Guez. There are a few busflow style tags in the photo too, but I can't read the names.

A large graffiti piece in black spraypaint on a white wall in a car garage. It shows bubble text letters merging with a skull character. I can't read the text, but the skull is very cool and very stylish.

Spotted in a garage on 18th and Mission. One of the pieces is by #Guez, the other is by an LA artist whose name I can't make it. #SFGraffiti #Graffiti

A glass door on an empty storefront. The door is covered with graffiti, including a drawing of a pitbull with a very thick metallic marker. Next to it are several drawings of a simplistic barbarian character. Then there is a bubble letter tag that says "Guez".

A photo of a big blue wall and garage door. There is a graffiti drawing of a mean looking dog on the door, drawn in brown spray paint with white fill. The dog is Guez's iconic character. The drawing is just of the head of the dog and it's spikey collar. To the side of the graffiti, you can see a man walking onthe sidewalk. The graffiti is about 7 feet tall and really pops out on the blue background.

Guez. Guez is a local graff-writer known for their iconic dog character, usually done in one continuous line. #SFGraffiti #Graffiti #Guez Shout out to the Sapien tag in the photo too.
