You forgot
And
And you need to remove Paris Hilton, Gaga, Katy Perry and Rihanna.
The only pop girls that are iconic in this sense are; Diana Ross, Aretha Franklin, Cher, Grace Jones, Tina Turner, Donna Summer, Madonna, Whitney Houston, Janet Jackson, Beyoncé, Britney Spears and the Spice Girls.
Anyway, I think you have to seperate the political and social figures from the artists and celebrities. Margaret Thatcher isn't in the same boat as Madonna. And maybe add a third category for icons like the Mona Lisa, Girl with a Pearl Earing and the Afgan Girl.
Did you add the Brontë sisters? They're pretty iconic in the book world.
