I have a few (some not scanned) in my collection 
(gallery down at the moment) of Ruka piloting her 
Mech. from the yakimo episode -- I really only 
wanted one... the first one I got was in a set of 
2 from the same scene... the 3rd & 4th ones both 
came with other cels of her I wanted... I think 
I'm going to be up to 5 when my latest package 
comes in.  The nice thing, though, is that the 
expressions are so different!

The only other cels that I have from same 
sequence/scene are from Tsukikage Ran... I have 
one cel of Miao cradling her friend in her 
arms... eyes are closed, but I managed to get 2 
extra cels of just her friends head just in case 
I ever find the arm layer that accompanies them...
(if anyone happens to have some nice pink arms 
with a big gaping space in the middle, let me 
know! ^^
