BMW's Clever Billboard for the M3 Coupe
BMW asked German ad agency Serviceplan to develop a billboard that "exceeds limits" at the Hamburg airport. Using a 50 x2 metre light wall in the middle of the arrivals hall, they designed a headline out of half letters. To complete the words, they used the reflection on the shiny floor. Through this process, they managed to double the media space for free.
