Reading/ Vinyl project

I thought Vandals or Visionaries? The Ethical Criticism of Street Art was a fascinating reading because I love when I see street art I think it gives the whole area so much more character. I don't really think street art should be illegal if people are using it for good causes like political statements or awareness. For my project I want to do some sort of political statement. I made a sketch about equality but I'm not sure yet if this is what I want to do.
