Wharf, the company that owned and operated Hong Kong’s famous Cross-Harbour Tunnel, wanted to mark the Tunnel’s 20th anniversary with an ad. It had to be congratulatory not smug; understated but not underwhelming. We dove deep and came up with this.

Did it work? All we know is that the ad picked up a gong in London and the Chairman had a copy framed for his office.
