Great Blondes of the 20th Century

There were only two Great Blondes in the 20th Century. If you're thinking Marilyn Monroe, Lana Turner, Kim Novak, or Brigitte Bardot, you're sadly mistaken. If you're thinking Jayne Mansfield, Reese Witherspoon, Anita Ekberg, Meg Ryan, Jean Harlow, Farrah Fawcett, or Pamela Anderson, you need to change your contact lens solution.
The two are, obviously, Grace Kelly and Catherine Deneuve.

Y'all can argue about third place all you want
(Tuesday Weld and Dietrich come to mind),
but the facts are the facts.
