This is a squared-up study for The Princess Badroulbadour, 1908 (Tate Gallery N03953), a portrait of the artist's three children in fancy dress as characters from the 'Aladdin' story in The Arabian Nights. The boy in the study is the artist's elder son, John. In the painting, his right rather than his left leg is concealed by his robes, and the drapery of his turban falls to his right shoulder. John was the Director of the Tate Gallery from 1938 to 1964. He is represented in a 1938 oil painting by his father, Portrait of Sir John Rothenstein C.B.E. (Tate Gallery T01869). The Tate Gallery also owns a second study for The Princess Badroulbadour (Tate Gallery T03682).
