Here is one book that I disagree with CGC's interpretation.... Love and Rockets #1 Fifth Printing. There is not a great sample size since these are two of the only three books on the CGC census, but here are two of them.
One copy is missing only the yellow ink with the exception of the very right edge. The other colors are not faded, only missing the yellow. The greens become blue, the reds become pink, the purples become brown and yet the blues stay rich and even (especially around the blue glove on the right side where the color change should be the most dramatic).
Any opinions?
