Portrait of Jacob de Gheyn III is a 1632 oil on oak panel portrait by Rembrandt of the engraver Jacob de Gheyn III, now in Dulwich Picture Gallery. It is smaller than most of Rembrandt's works, measuring only 29.9 by 24.9 centimetres (11.8 by 9.8 inches). It has been stolen numerous times and its size is one factor that has contributed to its numerous thefts.[1]
