“Serve Your Country By Saving Money” was one of many posters issued by the United States government during World War I to encourage people to buy War Savings Stamps (W.S.S). W.S.S could be purchased for 25 cents and, when enough were accumulated, they could be traded in for war bonds. This poster was commissioned by the U.S. government in 1918. The poster appeals to patriotism to raise support for war. The artist, Reinhold H. Palenske, was an American graphic artist and painter whose work is now displayed in the Library of Congress, the New York Public Library, and the Royal Gallery of London, England. This poster was created and reproduced as a lithograph at the time of its distribution.https://knowledge.e.southern.edu/wwiposters/1020/thum...
