Episode 183: The Nixie - Backstamps & Nixies

from Parcels of Knowledge

The Nixie is here! In the first episode of this new Parcels of Knowledge series, I dig into the smaller, stranger, and sometimes forgotten pieces of postal history. We start with two topics that fit together perfectly: what a "nixie" actually is, where the old postal term came from, and why we chose it as the name of the series; then we turn the envelope over and take a deep dive into the backstamp. We look at how backstamps documented a letter's journey through the postal system, the handstamps and markings used to create them, why the Post Office once required them, some of the surprisingly odd ways the backs of envelopes were used, and why routine backstamping eventually disappeared.The Backstamp is about the big picture; the journey of the Post Office, the NALC, and the people who shaped them. The Nixie is about the small stuff. Old postal objects, equipment, markings, words, forms, and practices that have disappeared, mostly disappeared, or survive in some weird little corner of the Postal Service. We pull one out of the historical mailstream, give it a closer look, and ask, "What the hell is this, and why did we have it?"Have an idea for a future Nixie, something weird sitting around your office that you have always wondered about, or an old postal term nobody seems to use anymore?
