Wooden ruler with inscription 'A GOOD RULE "Do Unto Others As You Would Have Them Do Unto You"' by Coca-Cola Bottling Company

This wooden ruler dates back to the early to mid-20th century, likely between the 1930s and 1950s. It was produced as a promotional item by the Coca-Cola Bottling Company, combining practical measurement with moral messaging through the Golden Rule inscription, which was a common practice during this era. These promotional rulers were distributed by businesses as advertising items that served both practical and educational purposes. Collectors of vintage advertising memorabilia, Coca-Cola collectibles, and nostalgic school supplies particularly value these items. The ruler represents the intersection of commercial advertising and moral messaging that was characteristic of mid-century American promotional items, making it appealing to Coca-Cola memorabilia enthusiasts.
