Spell it out and it reads “The European Fine Arts Fair.” TEFAF is one of the world’s preeminent organizations for fine art, antiques, and design, and it runs three fairs every year: one in Maastricht, the Netherlands, and two in New York City, spring and fall. Back for its fifth year, TEFAF New York Fall opens on November 1, but this time it’s a digital marketplace. Three-hundred dealers and 283 international participants are presenting in “masterpiece format,” with each exhibitor represented by just one piece. —E.C.
