Ephemera: the word derives from the Greek hemera and implies something that lasts for a day.

The term “paper” is often used to refer to ephemera, along with the phrase “printed matter.” However, not all ephemera is on paper but can also include items on metal, wood, cloth, celluloid, plastic, and other materials. And not all is printed. Some ephemera is far from transient. Some survives because of its importance, some was produced to endure for at least a length of time, some was made be collected and saved, such as postcards, poster stamps, and Victorian trade cards.
