ephemera n. - 1. anything short-lived or transitory. 2. an ephemerid
I have some ephemera that is over 100 years old. That doesn't sound short-lived to me. I just makes it absolutely precious!
SellaholicMom created a treasury on Etsy dedicated to all sorts of ephemera and I was pleased to be included. She has featured my music book which is over 100 years old. I even got to see the organ that this music was played on. How cool is that?
