In 2001, Disneyland released a 10-pin set that commemorated their trash cans. The set included pins denoting cans from the lands of Main Street, U.S.A., Tomorrowland, Fantasyland, Frontierland, Adventureland, New Orleans Square, and Mickey’s Toontown – as well as attraction-specific pins for the Matternhorn, Haunted Mansion, and It’s A Small World.
At the bottom of the packaging of what Disney called “The Art of the Trash Can” collection, they include the following “we must include something from Walt to justify this product” factoid: “In 1955, Walt asked the trash can manufacturer to modify their design by putting hinged flaps on the cans so that Guests could not see any trash… it started a whole new concept in trash can design.”
Whether or not that claim is true is questionable, but hey, it sold pins!
