Data is Plural: “Kangsan Lee et al. have compiled a dataset of “34,200 auction sales records, including images, artists’ attributes, and market information, encompassing 590 living contemporary artists spanning 17 years (1996 to 2012) across 23 countries.” It includes the artist’s name, nationality, and birth year; the artwork’s name, year, medium, and dimensions; the auction date, house, initial estimates, and final sale price; and more. The sales information comes from Blouin, which the researchers “cross-check[ed] with publicly available auction house data at the time, such as Christie’s and Sotheby’s.”
