"The Burlington Magazine", looking back at Clark's time at the gallery, singled out among the works acquired under his leadership the seven panels forming Sassetta's San Sepolcro Altarpiece from the fifteenth century, four works by Giovanni di Paolo from the same period, Niccolò dell'Abate's "The Death of Eurydice" from the sixteenth century and Ingres' "Madame Moitessier" from the nineteenth. Other important acquisitions, listed by Piper, were Rubens's "Watering Place", Constable's "Hadleigh Castle", Rembrandt's "Saskia as Flora", and Poussin's "The Adoration of the Golden Calf".
