Someone's comment: "Richter Koons Richter Koons... yawn". True, but strictly speaking it would have to be "Richter Richter Richter Richter". Note the difference between Richter's Net Value and, well, the rest.
Also, the variety in Koons's work over the decades is, arguably, much greater than Richter's (maybe that's the problem).
Someone else's comment: "All those Chinese, unbelievable. Don't know even one. Did I miss anything here?" Well, maybe. Though you would probably recognize Zhang Xiaogang if you saw his paintings, I get the point. In my unprofessional view, there used to be 3 kinds of chinese contemporary art. First, the classic style, drawings with calligraphic stuff, ink and watercolor. Second, the modern style, mostly paintings of depressive-looking chinese people. Third, the western art copycats with rip-off Richters and Polkes. The copycats - gone. Classic style: the older artists in the list. Modern style: the younger ones. And that's about it. Obviously, quite a few (chinese?) collectors invest in chinese art. And why not.(*)
Note: Where is Ai Weiwei?
What fascinates me ist not so much the chinese stuff: I don't know much about it and maybe it's just good or popular for some reason. But did you look at some of the names you know, below Richter and Koons?
I mean, Julie Mehretu ? Wade Guyton - 37Mio revenue? I don't understand. And what's so special with Peter Doig to make people pay 100Mios? What about Gursky and Schütte? Anthony Gormley? I don't want to disrespect these artists, but are they so much better than the rest?
Please, explain it to me.
