Ephemera spilosa

Ephemera (singular: ephemeron) are any transitory written or printed matter not meant to be retained or preserved. The word derives from the Greek ephemeros, meaning "lasting only one day, short-lived". Some collectible ephemera are advertising trade cards, airsickness bags, bookmarks, catalogues, greeting cards, letters, pamphlets, postcards, posters, prospectuses, defunct stock certificates or tickets, and zines.
