How did the economic boom affect advertising in the 1920s?

Marketers appealed to enhancing the consumer's image.

Explanation:

The United States was undergoing a great economic and cultural harmony, since the United States had just become champion of World War I, gaining holdings of several monopolies and winning several indemnifications.

American domestic trade is getting better and more profitable and this has influenced many aspects of the economy and culture of the United States of America.

Traders found it important to keep the image of the American consumer a good and prosperous image. This was because this was a time when exaggerated consumerism was embedded in American society, so it was important that the publicity removed this bad image from consumerism through ads that showed a positive image of the consumer.

this isn't a question and if you're going to list things be kind and use commas.
