Valentino's death mourned at grave site by Lady in Black for over 50 years.

Here's the earliest photograph I have of a Lady in Black (click,) mourning Rudolph Valentino, Aug. 23, 1937, 11 years after the movie star's death. In the first few years, memorial services were held on the anniversary, although the services eventually ceased and the large crowds dwindled to about 50 mourners.
