The medium-weight canvas is plain woven; it has been lined. The ground is pale gray or beige, thinly applied. The painting is executed in smoothly blended layers in the face and hair, with unblended, drier brushwork in the drapery; there is low brushwork texture in most of the lighter areas. The background gray ends in curved forms in the upper corners, as if the painting were meant to be an oval. The "signature" was found in 1965 to be a recent addition, applied over already abraded paint and readily soluble. The contours of the face and cravat, and parts of the hair, are severely abraded; the background is slightly abraded. There is a band of overpainted losses along the bottom edge, and more recent retouching along the contour on the right side of the sitter's face, in the bottom left corner, and above the "signature." The thick, natural resin varnish has discolored to a significant degree.
