Unlike the map of Casablanca, the map of Under Capricorn foregrounds its status as a "sign." It is quite obviously a page in a book, as evidenced by an unhidden wrinkle running through it and a printed page-border enclosing it. By contrast to the pristine graphic emblem of Casablanca, that of Under Capricorn presents itself not as an incorporeal symbol, free of material, worldly influences, but as a mundane object, rife with them; and the insistent artifice of the first shots of Australia realizes the anti-illusionist impulse of the presentation of the map.'
