Artist John Currin suddenly switched his gallery affiliation last week from his longtime New York dealer, Andrea Rosen, to Larry Gagosian. “Artists change galleries all the time, but Mr. Currin’s timing drew a great deal of attention. The show at the Whitney is the culmination of his 14-year association with Ms. Rosen, who gave him his first commerical gallery show, in 1992, and worked assiduously to foster and manage his success. Speculation about Mr. Currin’s move fueled conversation at art-world Christmas parties over the weekend, with expressions ranging from disgust to admiration for an astute business move.”
