What started in 1994 as a small fair by four ambitious New York gallery owners, today “spotlights the best 20th- and 21st-century art,” according to the Financial Times. This year marks an expanded curatorial program, with Nora Burnett Abrams, Anne Ellegood, Jamillah James, and José Carlos Diaz leading the way. Galleries presenting in this year’s edition? Simon Lee, Jeffrey Deitch, Sean Kelly, Victoria Miro, and many more. —E.C.
