The Image
I saw this image somewhere on Tumblr. I clipped it (presses it to be more precisely, using a WordPress snipped of code) as a draft post for future use here. Then it disappeared from Tumblr, but using search image of Google i got this search result from Google. Nifty! You just drop your image in the search box and see who has written about it.
The Campaign
Through Zuza Fun and Scary Ideas I learned this to be part of a CLM BBDO agency campaign for a newspaper, Metro News: Think For Yourself! It demonstrates even ad agencies can create street art. Love it!
