Classical concert halls. Where everyone is obsessed with the notes of Mozart and Beethoven…and not the location of the nearest McDonald’s. Knowing that, we created: the Jingle Board. At first, an OOH with no branding and then: an ear worm worthy of a symphony. McDonald's positioned the Jingle Boards in front of Germany’s most famous and most visited concert halls. The minimalistic OOH poster shows the musical note sheet of the world-famous McDonald's jingle.
