"Navy Had Map for Year Showing Jap Attack Plan" by Helen Buchalter, The Washington Daily News, December 10, 1941

The article suggests that the American Naval Intelligence was alerted to a possible Japanese attack more than a year before Pearl Harbor. It includes a map from a Japanese naval textbook showing a triple-route plan of attack in the Pacific, that seems to include the Hawaiian islands.
