8. Portrait of Dr Gachet 1890 Dr. Paul Gachet, who took care of Van Gogh in his last months. In 1990, it fetched a record price of $82.5 million ($75 million, plus a 10 percent buyer's commission). There are two authentic versions of the portrait, both painted in June 1890 in Auvers-sur-Oise, near Paris. Both show Doctor Gachet sitting at a table and leaning his head onto his right arm, but they are easily differentiated.
