The Metropolitan Museum of Art leads the way again. Their webpage the “MetCollects” introduces highlights of works of art recently acquired by the Met through gifts and purchases. Each month a new work is put under the spotlight. Click here to explore Jacob Epstein’s Mbunda mask from Zambia – which was acquired earlier this year. More than 20 detailed pictures let you closely inspect all angles from this mask; so next time you come across one you know how a good one should look.
