The Jack Agency specializes in urban communications, like this series of commercial graffiti created on the streets of London for Dr. Martens.

The ‘What Do You Stand For?’ campaign makes use of “clean graffiti,” which is applied with water, a power washer and a stencil, so that it leaves a design that is visible, but non-permanent and easily removed once the campaign is over.

For this Dr. Martens campaign, the stencils used were in the shape of an oversized boot imprint and location-specific to 10 sites, asking people in places like Bristol, Cardiff and Manchester “What Do You Stand For?” The urban artworks appeared over a period of four weeks, which would have been fun to spot as they appeared and disappeared over the course of time.
