What?? What is “Ephemera”?
e·phem·er·a - a class of collectable items not originally intended to last for more than a short time, such as tickets, posters, postcards, or labels.
Do you like to save your concert or movie tickets? Do you save little shells from your trip to the beach? A little vile of sand? A napkin from a wedding or event? A pressed flower from a special corsage or bouquet? Do you want a safe place to keep these little mementos? Put them in your scrapbooks.
