edit: sorry, I didn’t read your post. I don’t think Cai Guoqiang has done many paintings besides his gunpowder paintings, which are all one of a kind and not re-printed, as far as I know. I’d love a Yue Minjun print up on my wall, no doubt.
Cai Guoqiang has done some really amazing work over the past 2 decades. He showed at the Guggenheim in NYC several years ago. He also coordinated the pyrotechnics for the 2008 Olympics. He does work in all different mediums, but IMHO his most striking work is his gun powder paintings.
He has no shortage of breathtaking installations though, like “Head On” which features 99 (i think) eerily real handcrafted wolves crashing into a glass wall. His work is striking, technically impressive, and has a fair amount of social commentary to boot. Beautiful, thought-provoking work.
