I've seen two versions of the ending credits - 
the regular ones and the special ones that ran 
after the last episode. This cel isn't from 
either sequence. The regular end credits I don't 
think has cels - its all watercolor work. I *do* 
have a number of ep 26 ED cels, and this isn't 
like those at all. 

Yes, I won it on eBay ;) It was listed twice on 
YJ with a ridiculous start price, then on eBay 
when it didn't sell. And I'm not one to pass up 
a bargain, as it cost me about a third of what 
it would have run me on YJ. Thats the other 
reason I think its something...unique, as even 
OP cels don't start for as much as this one did 
(on YJ, anyway)
