Something I've been noticing with Cagliostro Production pieces is that they seem to have random gengas / production sketches included with them. Like with this one which looks like a shot likely from the end of Cagliostro

Also is some awesome Satoshi Kon pieces!

Also available are a ton of Studio Ghibli cels! Heres a few of them:

Some more Akira Backgrounds and some cels. Alot of Akira will be present in this auction

These 4 are some original Akira Production Hand Painted Backgrounds. Holy grail for anime collectors
