A portrait of a young man has been identified as the work of Rembrandt, making it the first discovery of an unknown Rembrandt since 1974. According to the Dutch newspaper NRC, the art dealer Jan Six bought the painting at an auction in 2016 following a hunch.

Six argues the case for the painting, which is supported by Ernst van de Wetering and fifteen other experts, in his new book Rembrandt’s Portrait of a Young Gentleman, which is published today by Prometheus in Dutch and English. Portrait of a Young Gentleman is now on show at the Hermitage in Amsterdam for one month.
