Sorry about that :) I'll try to hit the return button from
now on.
So what would you guys suggest?  layer with the signature,
or sign the cel itself?

As to selling them,  I never want to buy sells that I will
want to turn around and sell, but there is always that option
that a few years from now when I'm broke, I might have to
part with some of them.  So I just want to make sure that I'm
not "messing up" my cel.
