Methodology for data visualization: The graphs included in this report reflect all sales reported by Art Basel, sales reported directly to Artsy Editorial staff, and sales reported from Art Basel–specific gallery extensions (e.g. David Zwirner’s “Basel Online”). In total, 47 out of the 290 galleries participating in Art Basel in Basel (or 16%) reported sales. Sales were only included if a specific work or number of works were cited by the gallery. When a price range was provided, the low end of the range was used. All prices have been converted to USD.
