When America declared war on Germany on 6th April, 1917, it needed two things urgently: mass mobilization and public support. In other words, the US needed men and women who could sacrifice themselves and their money and time for the country. To achieve this feat, the U.S. government in 1917 felt obligated to promote a series of nationalistic messages through millions of newspapers, magazines, billboards, pamphlets, patriotic speeches, and propaganda booklets.
