The medium-weight canvas is plain woven; it has not been lined and the tacking margins survive intact. The stretcher is made of Eastern white pine, a native American species. The painting is executed fairly thinly with very low impasto in the highlights. The paint surface is badly abraded, and there are many losses resulting from the weakness of the canvas, which has several tears and is extremely brittle at the corners; there is heavy retouching in the hands, along the lower part of the painting, and in the upper right corner. The thick, natural resin varnish has discolored to a significant degree.
