It isn't. Shirley Temple was more apt to be called "America's Little Darling," "Dimples," or "Little Curly Top." Pickford was "The Girl with the Golden Hair" or "America's Sweetheart." Little Darling is close, but no dice. Anyways, Temple's mother specifically styled her hair after Pickford's-- who had contributed her talents to silent cinema since the 1910s, nearly two decades before Temple was born (and she didn't start her acting career until 1932). Ya gotta pay your dues to the creative hearths wherefrom talents derive their inspirations from.
