This year the two mainstays of the Frieze art fair—Frieze Masters and Frieze—are merging on a single online platform. Participating galleries number 250 and include all the headliners: Gagosian, Hauser & Wirth, Pace, and Galleria Continua among them. A curated section to look for is “Focus,” which supports the ultra young (15 and under!). Meanwhile, Frieze Sculpture will be on display in Regent’s Park, honoring the fair’s “commitment to the creative spirit of London.” —E.C.
