This image is a faithful digitisation of a unique historic image, and the copyright for it is most likely held by the person who created the image or the agency employing the person. It is believed that the use of this image may qualify as fair use under United States copyright law. Other use of this image, on Wikipedia or elsewhere, may be copyright infringement. See Wikipedia:Fair use for more information. Please remember that the non-free content criteria require that non-free images on Wikipedia must not "[be] used in a manner that is likely to replace the original market role of the original copyrighted media." Use of historic images from press agencies must only be used in a transformative nature, when the image itself is the subject of commentary rather than the event it depicts (which is the original market role, and is not allowed per policy).
