Another glowing example of how third-party grading standards really do a poor job assessing photographic issues from the 19th Century, particularly N172 Old Judge cards.  Clean and well-centered with a crisp, well-defined image, some edge and corner wear are the only noteworthy condition flaws visible at the card fronts.  The MK qualifier as well as the downgrade are largely the result of the card reverse, causing a reduction in the technical grade for a card that would likely grade VG or perhaps better if only the front were assessed.
