Publicis advertises crystal clear without posters

Just in time for spring cleaning, Publicis has come up with a special trick for Migros' "Glasklar" window cleaner: the APG poster frames contain nothing but a bottle of "Glasklar". This is not a revolution in poster advertising, but an absolutely clean product presentation by the Zurich advertising agency Publicis for the most effective glass cleaner of its client Migros.
