Painting, portrait of a woman in profile

Painting, old portrait of a woman. Height: 40 cm Width: 28 cm Mixed media. Painting done on an isorel plate itself covered with Gesso (or something similar). This gives this portrait a relief evoking an antique wall painting, as if this painting were a fragment. The edges are deliberately imperfect to reinforce the antique effect. Very beautiful unsigned work. Good general condition.
