That is a great cel!  You are so lucky.  It's 
such a fun scene.  What scenes are the other cels 
from?

I've been looking around for some Initial D cels, 
but like you said, there doesn't seem to be much 
around.  Taro has those two rather sad ones 
(especially compared to the one you just got).  
There was one on E-bay, but it wasn't a good 
shot.  If you find more that you don't have the 
money to buy, send the link my way. ;)
