1. Harold Ancart and Christopher Williams at David Zwirner Since 2013—the fair’s second year in New York—Zwirner has opted to show only solo and two-artist exhibitions at Frieze. This year, the gallery’s booth pairs rising art world star Harold Ancart, whose Public Art Fund commission titled Subliminal Standard debuted today at Cadman Plaza Park, and conceptual artist and photographer Christopher Williams. Both artists’ works were created specifically for the fair. Ancart, whose paintings and sculptures often take the natural world on as subjects, debuts paintings of larger-than-life matchsticks. Williams is known for his work examining the role of photography in our post-industrial society; his Frieze presentation includes five new photographs adapting and restaging his earlier work.
