How big has the Basel Miami art fair become? “Miami’s fair may do around $110 million this year. New York’s Armory Show said it took in about $45 million in March. London’s Frieze Art Fair reported October sales of $57 million, up 27 percent. Art Cologne closed Nov. 1 after taking in about $85 million. Including New York’s November auctions, collectors of contemporary art this fall may have spent more than $600 million by the time Miami’s fair ends on Dec. 4, based on published figures and fair directors’ estimates.”
