Fair use for Sky Masters
Though this image is subject to copyright, its use is covered by the U.S. fair use laws because:
 * 1) It representatively illustrates an educational article about a once popular, once widely-appreciated comic strip series of the past; its inclusion in the article adds significantly to understanding it because it is a historical sample of the art and story that are the subject of the article, and is covered in the critical commentary. Therefore the image substantially improves the article.
 * 2) The image is used as the primary means of visual identification of the article topic, which concerns visual art.
 * 3)  It is of much lower resolution than the original, and a very small excerpt of the volume of story produced. Any potential copies made from it would be of very inferior quality unsuitable for any commercial purpose. It is not used here for profit, and its use on Wikipedia does not compete with the copyright holder, and such use does not decrease the value of the copyright to its holder.
 * 4) It is not in any way replaceable with an uncopyrighted or freely copyrighted image pertinent to the article subject, because the whole body of work under discussion is copyrighted.
