Pieneman, Nicolaas – Jan Willem Pieneman (1779-1853). Schilder, vader van Nicolaas Pieneman, 1860 Rijksmuseum: part 2

The picture has something of this: people, portrait, man, sword, wear, knight, weapon, armor, Renaissance, music, facial hair, war, opera, cross, musician, festival.
Perhaps it’s a painting of a man in a brown coat and white shirt holding a paintbrush and a palette in one hand and an easel in the other hand.
