I've found that for some things, Cartoon 
Network's online shop is better than other 
dealers in terms of prices and selection. My only 
Futurama drawing came from them, and it cost $150-
-where shots of the same character of lesser 
quality (I haven't been able to find another 
sketch I consider better, except for the one I 
missed out on years ago) would easily sell for 
$100 more than I paid for it on a "private" 
gallery site.  American animation is expensive no 
matter what it is; whether it's overinflated or 
what I couldn't say, but that's how it is.
