Head of boy, in profile to the left

This delicate head study is datable to the 1640s, as proposed by Nicholas Turner who tentatively connects it to the boy in profile in Guercino's Prodigal Son, a recently rediscovered painting (M. Borchia, 'Dipinti come doni diplomatici [...]' Jahrbuch des Kunsthistorischen Museums Wien, 17/18, 2015-16, pp. 133-9, ill.). We thank Nicholas Turner for his assistance in cataloguing this drawing and for confirming the attribution based on a digital photograph.
