If you've gotten a confusion migraine from furniture assembly and/or you live in Vancouver, you'll appreciate Canadian retailer Urban Barn's "No Assembly Required" ad campaign by local shop Spring Advertising. They've put boxes representing park benches, fire hydrants and other public necessities all over the city to indirectly extol the virtues of pre-assembled stuff. Not that those virtues really need extolling, but it's still a neat idea. I'm also glad they didn't include a Porta-Potty box. That would have ended badly. More images after the jump. Via PSFK.
