Fair use rationale:
 * 1) There is no alternative, public domain or free-copyrighted replacement image that this artist has made, so if his work is to be illustrated, a non-free image has to be used.
 * 2) Its inclusion in the article(s) adds significantly to the article(s) because it shows  the work of the subject of the article(s).
 * 3) Inclusion is for information, education and analysis only. The text discussing the significance of this artist or art work is enhanced by inclusion of the image.
 * 4) The image is a low resolution copy of the original work of such low quality that it will not affect potential sales of the art work.
