Rationale
I (Matt Crypto) feel it is covered by the U.S. fair use laws because:
 * 1) The image is used for educational purposes only in a non-profit encyclopedia.
 * 2) The image is no larger and of no higher quality than is necessary for the illustration of an article.
 * 3) The artifact depicted is an historical cipher machine which is no longer in production or for sale.
 * 4) The use of the image on Wikipedia is not expected to decrease the value of the copyright.
 * 5) Its inclusion in the article adds significantly to the article because it shows the subject of this article.
 * 6) The image was likely a promotional image for the product in question.
