Delicacy and advertising combined in TBWA\Hakuhodo created for Japan's Suntory Whisky. The agency used a CNC router and a process that could be described as inverse 3-D printing to carve the designs.
Said designs varied from the Statue of Liberty to the Sphinx to Batman and everything in between. (There even appears to be, perhaps presciently, a Cannes Lion in the mix.)
Miwako Fujiwara of TBWA\Hakuhodo said the CNC router was chilled at -7 degrees Celsius to keep the ice from melting.
Launched in 2014 and just won a Branded Content & Entertainment Lotus trophy at the Asia Pacific Advertising Festival in Thailand.
