Frans Hals (Dutch, Antwerp 1582/83–1666 Haarlem), Portrait of a Man, Possibly Nicolaes Pietersz Duyst van Voorhout (born about 1600, died 1650), ca. 1636–38. Oil on canvas, 31 3/4 x 26 in. (80.6 x 66 cm). The Jules Bache Collection, 1949, 49.7.33 © 2000–2017 The Metropolitan Museum of Art

This brilliantly painted portrait can be dated on the basis of the stylish costume. Duyst van Voorhout was a Haarlem brewer, one of the most lucrative professions of the period. He had forty-seven pictures at the time of his death, but none of the portraits—as was common in estate inventories—is assigned an artist's name.
