Hmmm... I only have one backgrounded Ranma cel, so
I can't say for that in particular, but I can say
that just because it's stapled it doesn't mean
it's matching.  I've seen cels stapled before to
obviously non-matching backgrounds.  I have no
idea why some people choose to staple cels to
background, taping bags together is the way I
would choose (though bulky).

tome question the way she would like...
