Fair usage Summary and Rationale in the article Hungarian Gold Train
Though this image is subject to copyright, its use is covered by the U.S. fair use laws because:
 * 1) It is a historically significant photograph.
 * 2) It is of much lower resolution than the original (copies made from it will be of very inferior quality).
 * 3) The photo is only being used for informational purposes.
 * 4) Because the image depicts a non-reproducible historic event, there is almost certainly no free equivalent. Any substitute that is not a derivative work would fail to convey the meaning intended, would tarnish or misrepresent its image, or would fail its purpose of identification or commentary.
