This is by the artist GATS, which is an acronym for Graffiti Against The System. Faded but frightening.
Note the assisting finger of my well-manicured assistant. Looks like Zamar snuck into the middle of this one.
Sticker. Drawing. Not sure what the medium is here, I think it’s drawn on the sidewalk. Lovely image, hope it’s not vandalistically etched in the glass.
