Although the in-person fair has been postponed to October 2020, you can still pencil in the Dallas Art Fair, because online viewing is available during these long spring days of confinement. Eighty-four national and international galleries— including Kasmin, Perrotin, James Cohan, and Marlborough—are among the exhibitors. The site offers virtual tours of the spaces, fair highlights, and in-depth information about cutting-edge programming. For the first time, you can stroll around Dallas from your own easy chair. —E.C.
