“Ephemera, as artifacts of history, inevitably contains facts, prejudices, and other aspects (such as language, art and social organization) reflecting their particular time and place, and is now widely used in academic programs, sometimes falling under the rubric of ‘material culture,'” according to the Society. “Ephemera is revered not only for its content, but also for the beauty of its presentation which may involve interest in its graphic design, typography, a printing process such as chromolithography, or its format, such as a cobweb valentine.”
