History

The reply box is the most common single feature in this archive. An ad would end Address X 58, Tribune office, or Box 210 Tribune, and the paper held any letters that came in until the writer collected them. It let people advertise for a husband, a wife or a missed connection without anyone in town knowing who had placed the ad. Some writers used a pen name instead of a number, like Navy or Confidence at the Washington Evening Star.

The box number was the ancestor of the anonymous messaging inside a modern personals app: a way to receive replies without giving out your contact details.
