The canvas is finely plain woven; it has been lined, and there is an interlayer fabric between the two supports. The painting has been enlarged at the top with a strip of additional fabric 6.5 cm. wide. The ground is white, and is coarse and granular. The painting is executed in thin glazes in the hair, the shadows of the flesh and drapery, and the red brocade of the chair back, and in thicker, more opaque layers in the flesh tones and highlights of the costume, with slight impasto in the white fringe of the shawl. The "signature" has been shown to be false since it continues into cracks in the underlying paint film. The paint surface has been severely abraded throughout, especially in the thinly applied glazes in the shadows of the face and hands and in the hair. The abraded eyes, nose, and lips have all been reinforced, and numerous scattered losses in the head have been infilled. Some areas of the drapery have been heavily retouched, and the background has been almost completely repainted. The natural resin varnish has discolored yellow to a moderate degree.
