1962 Doyle Dane Bernbach ad for the VW Beetle:
Headline: 2 shapes known the world over.
Text: Nobody really notices Coke bottles or Volkswagens any more. They’re so well known, they blend in with the scenery…. (The only reason you can’t buy a VW at the North Pole is that the Volkswagen people won’t sell you one. There’s no VW service around the corner.) We hear that it’s possible to buy yourself a Coke at the North Pole, though. Which makes us suspect there’s only one thing that can get through ahead of a Volkswagen. A Coke truck.
