Jacob van Oost the Elder (1601 - 1671), Portrait of a Boy aged 11, 1650. Oil on canvas, 80.5 x 63 cm. Signed; Dated and inscribed. Bought, 1883, (NG1137) © 2016 The National Gallery, Trafalgar Square, London WC2N 5DN

This portrait is signed with the painter's monogram and dated 1650; the age of the boy is recorded as 11. The boy is turned away from the spectator, looking to the left. The design is concentrated upon the face and its expression, and the colouring is muted, enlivened only by the fur of the muff and the hat.
