Advertising Agency Mayer McCann Erickson in Bratislava, Slovakia recently help promote the Miele S8 vacuum cleaner with this awesome ambient outdoor billboard over a tunnel. This “Monster Suction” billboard was put up over a well-known tunnel in Slovakia and filmed what looks like cars and trucks being sucked into a pipe! Perhaps it’s safe to say this is one billboard ad that sucks, in a good creative way of course!
