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.
