The United States Postal Guide

Iron Age Ads: With post offices often being run out of the town's general store, advertising in postal guides.

| July 2007

In the 1880s, the (then named) U.S. Post Office Department implemented uniformity through a series of postal guides distributed monthly to postmasters. The guides included the letter of the law as it applied to postal matters and policy, updates and new information, such as (in the May 1882 edition) policies prohibiting shipment of plants to Romania, announcement of the acceptance of the Republic of Nicaragua into the Postal Union and division of the Davenport and Atchison route.

However, the guides also included paid advertising, not unlike the Yellow Pages of today's phone book. While the center of the book was given over to regulations and policy, pages at the front and back of the book were packed with ads.

Some ads were related to postal business (lock boxes, ink pads and rubber stamps) but most were for products of interest to the homeowner and farmer. In that post offices of that era often were conducted as a sideline at the general store, advertisers could count on high readership of a strategically placed postal guide - especially when they courted the postmaster as a business partner.

Postmasters were offered discounts and commissions on orders, and cash payments if they provided lists of homeowners and their addresses. From patent medicines to washing machines to horse powers, the postal guide was nearly as good as Sears & Roebuck. Today, the guides offer a fascinating look at the history of the American post office and farm and home consumer goods.
