Here is an original 1918 World War I propaganda poster illustrated by Adolf Treidler (whose name appears in the upper right corner) entitled "Help Stop This – Buy W.S.S. and Keep Him Out of America" published by the National War Savings Committee and printed by the W.F. Powers Company, Litho, N.Y.,  made in support of the war effort. It measures approximately. 9.5" x 14.5" and is an excellent condition with a blank reverse side. I have photographed it with its protective plastic sleeve on. It has crisp edges with no tears. It is a very striking image with great graphics and is a historically significant World War I propaganda piece. Thanks for looking at this auction.
