Thanks. These particular cels are my pride and joy.
I pay pretty close attention to eBay and various other animation/geek forums write to lots of collectors and dealers. The ones above, I got through a series of referrals that led to the owner of the Art of Akira exhibit. We ended up spending a lot of time chatting on Skype and in order to be able to buy them, I've agreed to loan them back to the exhibit on occasion.
Each of them is much larger than standard size and consists of anywhere up to 30 individual cels, paintings and sketches. The bottom two are the only complete 'set ups' (featuring the original hand-painted backgrounds) from those shots.
Needless to say, I have a very understanding wife.
