Hey Mandy, great picture series! I have not seen many of these pictures before.
Good idea to number them, too! Helps to identify which one you want to talk about/refer to. I think in picture #20 one of the women is Princess Benedikte of Denmark. It looks like her from the side, anyhow.
Corbis photo #56: The Silver Cruise: Edward behind the camera. Back row: Alexia, Nathalie - From front and backwards : Elizabeth Anson, Christina of Sweden, Count Flemming, King Juan Carlos.
