Owner Signs and Privilege Signs
Painted advertisements of that time period fell into two categories: Those referred to as "owner signs" which were sponsored by the owner of an establishment or building to represent their product or business name and those called "privilege signs" which were advertisements supported by national companies such as Owl Cigars.
The sponsors of privilege signs typically hired individuals to paint their images and gave the business owners a smaller credit on the wall for allowing them to use the surface of their building. The privilege sign below, found in Drummond, Montana, where rodeos are a part of the community, is likely sponsored by Lee Rider for their jeans in the late 1940's. The beneficiary of the advertisement is Greany's Dry Good Store, who sold the pants.
