An ad in the back of a 1930 edition of The Bulletin, AMC’s newsletter at the time, offered these items, embossed with AMC’s initials and “not readily attainable in the stores,” for 20 cents. A year later, The Bulletin reported sales of 401 cups.
The simple, lightweight vessel has endured, even if its origin hasn’t. Although commonly called “sierra cups” today, thanks to their popularization by the Sierra Club, the cups’ design can be traced back to AMC. In Voices for the Earth, a 1979 anthology of Sierra Club stories, Ann Gilliam wrote, “If there is a badge and symbol of this organization it is that most useful of all mountain tools, the Sierra Club cup…patterned after a similar design used by the Appalachian Mountain Club.”
Further evidence comes from David Brower, the Sierra Club’s first executive director, who admitted in his 1990 autobiography, “the Sierra Club imitated the Appalachian Mountain Club’s cup, but that is a secret.”
