This Qing Dynasty six-inch jade brushpot just sold for $2,060,000 at Sotheby's. It depicts an imperial procession.
For the previous 118 years it was in the collection of the Art Institute of Chicago - but I don't remember ever seeing it.
I doubt that it has been on display recently. The gallery space for Chinese art was reduced significantly when the Roger Weston Galleries of Japanese Art was installed in 2010.
Here are some detail views:
I would call this a treasure of world art.
It may be easier to see in these large photo images than it would be to examine all six inches of its physical presence -- but still -- I wish we could try it sometime.
As usual, the Art Institute made no announcement of the deaccession. Many thanks to Matt Morris for bringing it to public attention
Hopefully, one day it will return to view here in some kind of special exhibit.
