Forgive me if this has been pointed out before; I did not comb through all 60+ pages in this thread:
I call this the "horizontal line between a foul pole (?) or otherwise two vertical lines" in the '63 Clemente. See 2nd pic. The horizontal line doesn't appear on all of them.
This would not appear to affect the grade, as I've seen otherwise sharp copies "with horizontal line" in high grade slabs. I always kind of considered it a printing error, but I guess not everyone does. What is this, does anyone know? Roller mark? Hair or some other detritus left on a printing plate?
