Scanner-novice that I am, I just spent most of the 
evening fumbling my way through my latest 
acquisitions.  I found so many surprises among my 
new Tenchi cels (oversize cels, key cels).  But I 
found one thing that is TOTALLY new for me.  I 
hope somehere here can educate me.

The backgrounded Ayeka cel I've dubbed "Friar 
Tuck" (pic at the link above) had some 
overlooked goodies.  Two matching sketches!  Which 
indicated both layers were key!  And this sketch 
of the background???

I didn't see anything like this in the cel FAQ....
