Jan Anthonisz van Ravesteyn (and studio) – Portrait of an Officer Mauritshuis

The picture has something of this: people, weapon, portrait, sword, armor, wear, military, man, soldier, war, helmet, uniform, military uniform, knight, gun, skirmish, lid.
Perhaps it’s a painting of a man in a black and gold outfit holding a sword and wearing a helmet with a feather on top of his head and a feather in his hand.
