UK-based street art media provider creates "green" graffiti

UK vendor, Street Advertising Services, sends out street teams to do eco-friendly guerilla marketing campaigns for their clients. These street teams use high pressure sprayers to wash the client's stenciled logo or message right into the sidewalk or street. The process involves just water and steam and is 100% environmentally safe. I never thought I would see the day when sustainability and street art converge. "Green" is becoming a standard in our world.
