As you can see in the image below, a screen short from The Economist article here, Mark Rothko is the male artist with the highest-selling at auction artwork, for Orange, Red, Yellow which was bought for $86million while Louise Bourgeois leads the female post-war artists with her work Spider selling for $10million - a whopping $76million difference between the highest post-war selling artwork by a male and female artist.
While the figures are certainly depressing, Amy Cappellazzo, chairman of post-war and contemporary art development at Christie's, told The Economist that attitudes towards female artists are changing, generationally. "It wasn't long ago that it was hard to be taken seriously as a woman artist. There will be some remedial catch up before women artists have parity on prices."
