Portrait of the artist holding an academic drawing Luis Eugenio Meléndez (1716-1780)

The picture has something of this: wear, people, portrait, outerwear, jacket, woman, man, coat, facial expression, lid, veil, seat, outfit, furniture, fashion, scarf.
Perhaps it’s a painting of a man holding a pencil in his right hand and a drawing of a man’s torso on a piece of paper in his left hand.
