I am only aware of one vacuum cleaner that was ever given the "official" designation: Electrolux USA's Olympia One (model 1401-B) which was the official vacuum cleaner of the 1980 Winter Olympics in Lake Placid, NY.
Have there been or are there others (Electrolux or other brands)--either for the Olympics or other event or cause? If so, were they also affixed with a special decal like the Olympia One was?
