Here's a cute marketing campaign by Saatchi and Saatchi London for Carlsberg. A total of £5000 in £10 and £20 notes were individually dropped around the streets of London with a green removable sticker that read, Carlsberg don't do litter. It is also a public service campaign but I am not sure how that can be associated with the Carlsberg brand. Anyone please tell me the CPM for his campaign?
