Advertising

In 1967, Hiram Walker & Sons launched their "Hide A Case" advertising campaign that enticed drinkers to seek out cases of Canadian Club hidden at exotic locations throughout the world, including Mount Kilimanjaro, Angel Falls, Mount St. Helens and the Swiss Alps. The Mount Kilimanjaro case was not discovered until a Dutch journalist happened upon it in the mid-1970s. A small number of cases, such as one hidden above the Arctic Circle, were never found.

The first "Hide A Case" campaign officially ended in 1971. A second was started in 1975, where cases were hidden in places intended to be easier to access, such as in Death Valley and on top of a skyscraper in New York City. This second campaign ended in 1981; between it and the first, 22 cases were hidden and at least 16 recovered.[6]
