Just after reading Ryan Carson's two posts about airport advertising, I was in Johannesburg airport yesterday and noticed these:
The clever bit is in the placement. Jo'burg airport is currently undergoing a big extension project during which time there is a long walk between the international terminal and the domestic terminal. All along the walk, these huge adverts for Jonnie Walker provide encouragement with their slogan "Keep Walking". Other quoted persons included Albert Einstein, Nelson Mandela and Yoda.
