For more info about the artist, see: Frida Kahlo (1907 – 1954).
There is a movie 〈Frida〉 directed by Julie Taymor, 2003. amazon Mexican actress Salma Hayek starring the artist. (Julie Taymor also directed 〈Titus〉. See: Julie Taymor's Titus)
Note that Frida has painted lots of self-portraits, but the book cover has to use a actress instead. What degree of insult is this? It is that way because it sells, and selling is important because the social structure of capitalism. And, it sells that way because in modern society, people are far more aware of movies than historical figures. The other reason, is because the size and structure of modern society, where no amount of education can we expect most people to know most of the important historical figures. There are too many, too big.
The use of a movie to sell a biography can only be temporal. The immortality of a artist lies in her work along.
