On October 5, 1973, the USPS issued the first of three stamps in the Rural America Series, which honored different aspects of rural life in America. The first stamp in the series featured an image of an angus bull with Texas longhorns in the background. It was based on a painting by Frank Murphy, a leading agricultural painter. The stamp was issued in St. Joseph, Missouri, at the headquarters of the American Angus Association. The first day ceremony was held just after the end of the World Angus Forum and marked the first stop on the Centennial National Angus Tour.
