So Oatly wanted to launch in Paris, which apparently could only have billboards with more "art-oriented advertising" (that's the story I read anyway). So the trick they resorted to? They went all out with negative messages about advertising on that specific wall... Only to subvert the message by different means. Either a forklift with boxes, a porta potty, or a full van. Now of course, with Paris inhabitants actually speaking French, it is interesting that the ads are in English - but side note: Cannes juries are often anglophone (cough, ahem!).
Well of course, the campaign is indeed thought out well creatively, that is for sure. Whether this drives sales or is just a gimmick remains to be seen!
