Jon Jackson, a Los Angeles-based designer, is skipping town for a creative-director job at Huge in New York. But first, he's ending it with L.A. properly by placing five breakup billboards around town. The AdiosLA site explains: "Paul Simon never mentioned this. You can slip out the back Jack or you can put up five 10 x 23 foot billboards in your neighborhood. ... Not wanting to string L.A. along, [Jackson] has decided to firmly break it off through a graphic billboard series posted on the famous streets of his first love. Most take Mr. Simon's advice when leaving town, but if you want a city with benefits, you better do more than make a new plan, Stan." The ads will be up through Jan. 15. "Bring a camera and box of tissue," Jackson advises. The AdiosLA site also includes Google Maps integration and iPhone background images. Fun idea, wonderfully executed. Via AgencySpy. UPDATE: Huge tells us it had nothing to do with the stunt, but the agency has decided to cover the costs of the project anyway.
