Commercial and public service announcement for ZIP Codes; male voiceover: “They just don’t make things like they used to, right? It’s always the other guy who’s slow or careless! But you do all you can-or, do you? Every letter you send without ZIP code requires extra sorting, slows down the mail! Put the ZIP code on every card, letter, and package you send! Remember: mail moves the country, and ZIP code moves the mail!”
