Old items and creations that could be brought back

What old items and creations do you think could be brought back and possibly re-purposed for a different use? I believe that milk doors (storage boxes that people had decades ago for the milk man to put milk into one side and for the owners to get out of the other) could be brought back but with the new use of having the mail or usb delivery man to put mail, packages and itens from Amazon and other online sites into to store and protect said mail, packages and items from potential thiefs and allowing the people of said mail and items to get out of the other end.
