I should point out something that you may or may
not realize when searching for that particular
cel.  The transparency of her veil is probably the
result of a special effects technique (double
exposure).  The actual cel will probably have the
veil painted solid white on a separate layer.  If
the layers have been stuck together only her mouth
would be visible in the seller's scan. 

Compare the screencapture of Queen Tahomine to the
actual cel.
