Interesting. So, what I think I am hearing is if it is part of the art then it shouldn't get downgraded unless it damages the book otherwise (like what Ron C. indicated) or the artist does some sort of obvious touch up work to the blank cover (like what Par2ch indicated). What about ink smudges that are created during the artist's creation? Is that not considered part of the artist's manner in creating said art? Maybe I am off but it seems like smudges happen (not always - but enough) during the artistic creation. I believe I have seen posts on the boards before referencing books getting downgraded because of smudges (for example: slight smudging on the back of the cover when the sketch is on the front). And I have my own stories I could share about it as well. How is ink smudging any worse for grading than cutting, burning, scraping, etc. a cover? I guess I am confused what's the line for grading art on a sketch cover - what if an artist accidentally over cuts a cover, over burns a cover, over scrapes a cover, etc. more than the intended art (and would CGC even know)? And is there a difference between pencil smudges vs ink smudges? What if the smudging happens on the same cover as the actual art - will that be downgraded too? What if you got the sketch colored and the colorist colors outside of the lines!?! I understand flaws on a book (i.e. bends, folds, color breaks, creases, etc.) may downgrade a book - but is an artist's smudge (during the creation of art) in the same category as those physical flaws? Again... interesting...
