The book Wally gets at the library for Penny is the 1903 classic "Rebecca of Sunnybrook Farm", written by Kate Douglas Wiggin. Before 1957, the story or some permutation of it had already been made into three movies: Rebecca of Sunnybrook Farm (1917) with Mary Pickford in the title role, Rebecca of Sunnybrook Farm (1932) with Marian Nixon and Rebecca of Sunnybrook Farm (1938) with Shirley Temple.
