Well, sometimes the seller doesn't know there's 
been chipped paint.  On some of my cels, when I 
try lifting the layers...Just one hint of 
sticking, I don't try lifting any 
further...Especially on older cels.  As far as 
faded trace lines go...If it's a major change 
from what you saw in the original image...Then 
I'd ask the seller about it...But, you have to 
understand that...Lines DO fade...There is no 
stopping it really.  And...Sometimes studios 
actually do that in the production process for 
the effect they want on the cel.

All-in-all...If you're happy with the cel...It's 
all good.  And if the damage isn't major...I 
wouldn't worry too much about it...And I do have 
to agree with the other poster...You buy the cel 
as is in a scan...Sometimes the seller doesn't 
know that condition of the cel...And to of really 
know...Asking questions before hand would have 
been the best route to go.

Don't worry...You're not alone...one of my most 
expensive cels...Peaking around $1k...I bought 
and when I received it in the mail had the 
background colors leaking through the top of the 
cel...Something you can't get rid of...And 
something that's MAJORLY visible.  But...I bought 
it without asking any questions...So I'm stuck 
with it...My fault for not asking questions is 
what I've come to conclude >.
