Very Rare World War I Poster Extolling the Contributions of Women in Uniform

Illustrated by Clarence F. Underwood and published by the YWCA, 1918, this poster shows a woman operating communications equipment inside a booth with soldiers marching in the background. It features the message ""Back our girls over there, United War Work Campaign"" in the lower right hand corner. During World War I, the U.S. army recruited women to serve as telephone operators. This is one of the few World War I posters showing a woman in uniform. Fine condition, backed on linen.
