"BIG JOE" CAN BLAST A HOLE THROUGH A FOG! . . . It's the air raid siren that's guarding Pearl Harbor and hundreds of American towns and cities . . . and it's got the loudest mechanical voice in the world today.  It can actually start fires with its tremendous vibrations! . . . "Where does Big Joe's power come from? . . . I'll tell you! . . . From the same engine that used to hide under the hood of a Chrysler . . . the very engine that's helping to push thousands of General Sherman tanks toward Berlin and Tokio!"
