One the winners of the recent Cannes Advertising Festival: Quorum/Nazca Saatchi & Saatchi PerúPapa John's, pizza service. Instead of the annoying leaflets left in the mailbox, the agency came up with this intrusive yet original idea: a sticker attached right below the peephole with the image of a pizza boy plus, of course, the number to call.

The ad won the Gold Lion for the best use of alternative media in direct marketing.
