To me, it's like asking a used car salesman how he would rate a car he's selling. What do you expect him to say? I mean seriously, the guy actually provided some pretty clear photos, which makes him an overachiever by eBay standards. What is the point in asking him to put a number to something that you can clearly see and judge for yourself? Is anyone really going to base their decision on that rather than the photos?
"Gee, I was trying to figure out which photo showed the signatures, but if he says they're at least a 5 then I'm all over this one!"
