Is this foxing? 3 3

Asm129 9.4 (w). Grader notes only specify light spine stress lines. I'm wondering if that light brown half circle on the bottom back cover is just really well condensed foxing.

A stain, I would think, would be lower grade and noted surely.

Looks like foxing.  I don't think it would have been from condensation.  Could have been present when graded, or have been lighter when graded and since "aged". 

I have had graders knock a likely 9.6 down to a 9.2 for foxing, and others knock a 9.6 down to a 8.5.  So, as I say, it could have been there. 

Grader notes are not necessarily comprehensive, just notes for other graders further down the line.

As Lightning 55 said, grader notes are not necessarily comprehensive but it looks like a water/moisture stain not foxing to me.

Not foxing. 

[Lightning55]

I stand corrected. Foxing generally presents as an array of brown or tan spots. They are caused by microbial activity, fungus related. This particular stain looks more like water/moisture damage as @ Pontoon suggests. 

If this was graded very recently, which it wasn't, there would front and back images at the time of grading on the lookup page, to compare. Then you could see if there was any change in condition from there.

I can't say that I agree with the 9.4...

That's a stain and may or may not be water.
