  1. Thank you for that. I had heard something about newton rings before, but didn’t know if this was an example.
  2. Was looking at this book and noticed on the back these blotches on the back edge and top. The graders notes doesn’t say anything about them and the grade is cgc 9.2. Was just wondering if this is from something that occurred after the book was slabbed? Is it just the lighting? Any help would be appreciated.
