Chicago Board of Trade II is a colour photograph by German artist Andreas Gursky made in 1999.
It was created following his usual process of taking several pictures of the same subject and then manipulating and merging the scanned results by computer.
Tate Modern website describes it: "Rather than being a straight depiction of the trading floor as a place, Gursky’s image seems to depict the brash, exuberant and unfathomable activity of the stock market as a global phenomenon.
[3][4] A new version of the picture, Chicago, Board of Trade III (1999-2009) would be sold by $3,298,755 at Sotheby's, London, on 26 June 2013.
