I looked at the huge scans. If you haven't looked at those you should.
The white spot near his knee looks more like some lint in the holder.
The corners do show just the slightest wear. I only figured two, but won't argue if someone else sees three.
The marking on the back is an offset transfer, both red and brown. (And if it's from storage there might be another wagner just as nice!)
What looks like a scratch on the knee at the right I think is on the holder.
The white dot at the lower right and the one at the top center are too small to tell even from the huge scan. They're probably just print defects. If they're paper loss then things are very different.
The red is off register slightly low and left.
I don't think I'd be as harsh as calling it a 1-3, even if the two tiny spots are missing paper. Maybe a 4.
If they're just print defects, I'd be thinking more like 9-9.5, far from perfect with 4-5 trivial defects, but still extremely nice.
And still way more than I could afford, probably more than my house
