Buenos Aires, Argentina. There’s a book devoted to BA street art. In walking around the suburbs, street art is quite acceptable. Without too much effort one can see artists at work. One woman in this series of images was working right in front of a school. I saw another artist spraying clear varnish to protect his work from the weather. Others worked in plain sight within a playground. I don’t know the rules for who decides where an artist may work. Much of what you see is in the neighborhood of Palermo, a wealthy suburb not too far from the main city center. My son was working nearby and living in a building with a pool and hot tub on the roof. He also had a great view and great sunsets.
