clean graffiti

In recent days this 'clean graffiti' has cropped up on pavements near where I live advertising a new burger bar in Cotham. Though I've been aware of this guerilla-advertising-type process for a while it's the first time I've seen it for real (the effect is produced using high-pressured steam cleaners over a stencil). I guess for branding purposes it works quite well (after all, here I am writing about it, though that's only because I've never seen it used before). Whether it'll convert into paying burger-consuming customers is another thing. We're in uni-land here, close to the Whiteladies strip, so if this stretch of paving hasn't reverted to its normal grubby state by October then I'm sure it'll get noticed by its target-market. I just wonder, though, if they've missed a trick by not stencilling direction arrows all the way down the street to the bar itself. Not that I condone the insidious reach of advertising into our everyday lives, but just an idea...
