Full-building graphite are one of the hallmarks of downtown Belo Horizonte. I remember as a kid seeing some of those impressive, surrealistic images. They made a big impression on me, I wish I knew who the artist(s) was/were.
Indeed. Most of the markings are low-effort territory marking. At least they aren't peeing on walls.
Maybe if we added arts to the basic school curriculum some aesthetic sensitivity could be imparted in them so they'd feel pressed to better consider what they are going to paint.
