Vintage 1918 Liberty Loan WWI Patriotic Propaganda Art Poster

This original-style 1918 poster by J. Allen St. John, issued as a supplement to Engineering & Mining Journal on September 21, 1918, shows a woman wearing the Statue of Liberty's crown holding a candlestick telephone, with the urgent headline 'HELLO! THIS IS LIBERTY SPEAKING – BILLIONS OF DOLLARS ARE NEEDED AND NEEDED NOW.' A fascinating piece of American wartime ephemera for history buffs and collectors.
