Don't they all come with the production sketches 
for the scene? I thought that was one of the 
attractions of the post-production cels. (Note: I 
know nothing about these things further than that 
they exist. ^_^;)

I have to say, there are few series for which I'd 
consider post-production cels. ^_^  It's a little 
bit of cheesy marketing, but seems like more fun 
than just the sketch. ^_~
