(Original Caption) Castles Were in Her Future. Ocean City, N.J.: Film actress Grace Kelly has disclosed to the world that she plans to retire from the movies to marry Prince Rainier of Monaco. It is a storybook romance come true. She met the handsome prince on the Riviera last year when she was making a film there and it was "love at first sight." The lovely star will live in a palace on the Mediterranean. Here, in a 1937 photo made at Ocean City, N.J., Grace and her sister Peggy (Margaret) (left) fashion a sand castle on the beach. She was 7 years old at the time. Margaret was 12.
