The venerable 28-year-old Tefaf, Maastricht art fair is the latest to shake up the art market calendar by announcing today that it will launch two editions a year in New York, starting this autumn.

The European fair, which sells art from the ancient to the contemporary with Old Master paintings at its core, has joined forces with Artvest Partners, the New York art advisory firm that runs the Spring Masters fair held in May in the Park Avenue Armory.
