Rembrandt Harmensz. van Rijn – Portret van een man, misschien Rembrandts vader, Harmen Gerritsz. van Rijn, 1634 Rijksmuseum: part 1

The picture has something of this: people, lid, man, wear, veil, sword, portrait, armor, soldier, knight, military, Renaissance, vintage, mustache.
Perhaps it’s a close up of a painting of a man wearing a helmet with a feather on top of his head and a feathered hat on his head.
