ARTnews compiles its annual list, in a super-heated market. “Last year at least 810 works of art were sold for over $1 million at auction, according to Artprice.com, which added that we should keep in mind that ‘until the end of the 1990s only 100 to 200 auctions per year broke through the million-dollar threshold.’ At least 200 works went for more than $1 million at the recent auctions.”
