At the Toronto International Film Festival (TIFF) in Canada, communications Company Lowe Roche has stuck hundreds of 1:43 scale Audi quattro models to metal surfaces as part of an ad campaign by Audi.
Fitted with strong magnets and stuck to lamp posts, newspaper boxes and the like, passers-by were encouraged to remove the die-cast models and take them home with them. On the underside of each model is a sticker that reads, "Nothing sticks like quattro."
