An rare original 1955 U.S one sheet poster for the theatrical release of The Swan, an American romantic comedy directed by Charles Vidor, starring Grace Kelly, Alec Guinness and Louis Jourdan with Agnes Moorehead, Jessie Royce Landis, Brian Aherne, Leo G. Carroll, Estelle Winwood, and Robert Coote. It's a bittersweet fairy tale of romance and royalty that in many ways eerily predicts Kelly's future marriage to Prince Rainier of Monaco and her life as a princess in a small European country. The film was released the day Grace Kelly became Princess consort of Monaco.
