The like 30 princess mononoke cels that mandarake 
brought over from japan like the week before.  I 
thought I was going to have a heart attack.  Not 
to mention that I missed out on a great 
opportunity to get a really cheap one(well as 
cheap as you could get for mononoke, stinking 
needing to buy a house).  It was amazing the 
range and quality of them.  Everything from the 
wolves to ashitaka to one of my favorites a close 
up of the forest gods head after being 
decapitated.  It was breath taking.  

Anime-link also had some amazing cels as Brian 
commented on.  Had to restrain alot.  New vampire 
hunter D cels.  Wow I want to see that movie alot.

There were some others of mention, but those were 
my favorite.
