The 1895 N300 Mayo"s Cut Plug set is popular among 19th Century collectors. Unlike the N172 Old Judge set which features black and white photos that often suffer from fading and discoloration the N300s feature photos that are sharp and clear. Still the N300s have condition challenges of their own since their black borders are prone to chipping and the backs are often damaged due to being removed from scrapbooks. Occasionally for unscrupulous reasons and occasionally for innocent reasons of improving appearance, collectors would attempt to repair chipping within this issue by adding color to the borders or background.  Such appears to be the case with this example, graded Authentic by SGC with color added.  Still, an attractive, collector-grade card from a popular 19th Century issue.
