When ad agency JWT Hong Kong was assigned the new Listerine campaign, they used their creative minds to come up with the bad breath flipbook. Their goal was "to convey the message that Listerine effectively eliminates bacteria and bad breath after eating." The book has a photo of an attractive girl, and when you flip through the pages, it emits an onion-like odor. The back of the book has a coupon for free Listerine. [JWT]
