The support is a medium-weight, plain-weave fabric. It has been lined, but cusping is present along all four edges. Stenciled on the reverse of the original canvas is "WILLIAMS & STEVENS / 353 / BROADWAY / NEW-YORK." The ground layer is thick, smooth, and white. Flesh tones are blended with a minimum of impasto, while the garments are painted thickly and opaquely. In the olive background, an appearance of a slight, swirling texture was created by a thin layer of glazing laid down over more thickly applied paint. Small losses and areas of inpainting occur in the sitter's hair, at his hairline, and on his coat. A tiny cut or puncture is evident in the upper left part of the background. The evenly applied varnish is heavy and has discolored.
 The original stencil mark, now concealed, was copied on to the reverse of the new lining fabric.
