An unusual reading woman--Rembrandt's Mother as painted by Gerard Dou (1613-1675), an artist whose work I am unfamiliar with. He was one of Rembrandt's pupils and painted mostly genre scenes. This painting resides in the Rijksmuseum.
The middle stamp is about compensating for CO2 emissions. The only thing I can find about the colorful stamp on the right is Royal PostNL.
