There is a guy in jeans and a grey T-shirt kneeling down on the sidewalk with a can of spray paint in his right hand.  The wall that he is painting is red and has bright green and purple graffiti covering it.  There are two other figures in the background of this picture.  One appears to be taller than the others.  You can see the sidewalk in this image with chalk art on it.  There are many cans littering the sidewalk.
