Intelligent graffiti

I was cycling with my kids through an underpass in Gorton and saw this I will try and update this list and ig you could add to it please do.
  1. Who knew the PX Crew were into electoral integrity
  2. Spokane, Washington 1981
    My college boyfriend and I were visiting my parents and took a walk along the Spokane River a short ways from the city. We found this literate graffiti under a bridge. I like to think it was a message from one of the area's Gypsy groups to someone they weren't too impressed with. (I don't mind the misspelling at all. Adds character.)
