Some 450 of these posters are part of the San Antonio Public Library's permanent collection, bequeathed in 1940 by Harry Hertzberg, a Texas state senator and avid memorabilia collector. The posters were created by a group of early twentieth-century American artists, among them Charles Dana Gibson, Howard Chandler Christy, James Montgomery Flagg, Guy Lipscombe, Charles Buckle Falls, Haskell Coffin, and Norman Rockwell. The lithographs' heroic images and patriotic slogans depicted military and civilian effort and sacrifice, aiming to inspire young men and women to enlist, pick up a flag, and support the soldiers and nurses during a trying time in American history.
The posters, many of which appeared on the cover of the Saturday Evening Post, are both testaments to the people who volunteered their service and excellent examples of the period's advertising strategies and graphic design.
