Portrait Of A Carthusian Petrus Christus (1410-1476)

The picture has something of this: portrait, people, man, facial hair, wear, model, fashion, side view, facial expression, mustache, face, profile, veil, eye, woman, nude.
Perhaps it’s a close up of a painting of a man with a long beard and wearing a white robe with writing on the side of his chest and a red wall behind him.
