I spent quite a while exploring the site yesterday - thanks for posting it.
It's very interesting to see the painting and the photographic image side by side, Frida looks a little frailer (and younger) in 'real' life. Though still with a very powerful and expressive core.
I like being able to see all the different pictures of her. Probably we would all choose a different one as our favourite. Seeing them all gives a real sense of the person.
