Less frequently-seen N172 card of Hall of Famer John Clarkson, graded FR 1.5 by PSA.  Though PSA generally does not address image quality when grading N172s, in this case it appears that chipping to the heavily-toned image is responsible for reducing the technical grade.  The image itself does exhibit some fading, but the fading is probably as much related to the toning as it is actual fading.  Regardless, the image is still visible and the text legible, with four square corners and decent centering.
