Brisbane is hosting a spectacular new aquarium event titled Brisbane Underwater City, where the public can come face-to-face with all manner of marine life. A logotype and billboard advertisement were required to promote this family event, communicating a sense of adventure and wonder. The logotype provides a simple visual link to the city being below the waterline, while the billboard uses a photo montage to present Brisbane as a kind of ‘Atlantis’, hidden away in the depths of the ocean, waiting to be discovered.
