Trubetskoi's collection included a Rembrandt portrait of a young man holding a black hat (now in the Armand Hammer collection, Los Angeles) and Madonna and Child by Jan Gossaert. Both paintings were formerly in the collection of Prince Gagarin, who lent the Gossaert (now NGA 1981.87.1) to a charity exhibition in Moscow of pictures from private collections in 1892.
