Magnetic Paper Promoted In Roundabout Manner

Chicago Agency Hadrian's Wall has created an interesting campaign for its client Magnecote paper. Rather than simply advertise the product to its target, agency creatives and production people who can use the stuff to make magnetic posters, Hadrian's Wall took a different approach. They chose a public service cause, World Bicycle Relief, enlisted seven other agencies to create PSAs for WBR. Magnecote agreed to produce the campaign, WBT agreed to run it, the campaign had to use Magnecote paper and each campaign would be voted upon by the public. Now isn't that a whole lot more interesting that just placing a few boring ads in Creativity for a product as boring as magnetic paper?
