Real name, Paul Curtis, Moose is the grand-daddy of reverse graffiti. He’s been cleaning the streets of the UK and beyond for around ten years.

Using detergent and a wire brush, the tools of many a cleaner, he works with advertisers to create innovative clean messages and slogans that inevitably turn into works of art.

One of his more recent works, the Reverse Graffiti Project, was on San Francisco’s Broadway tunnel in conjunction with Green Works, to promote a plant-based cleaner.
