I'd love a cel of Tetsuro's mother up on that
robot royalty's wall. (Okay, so I have freaky
tastes...)

Princess Tiffany cel from My Little Pony & Friends
or a background of any of the MLP castles. 

Starlite from Rainbow Brite! I've seen very few RB
cels and none of Starlite at all.

A cel of that purple flying horse from the fruit
snacks commercial in the '80s/early '90s. I have
no idea what the food used to be called, but I
remember the other chewies in the package were
bears. (Anyone picking up a trend here? ;)

The KITT car from the photograph episode of
Dexter's Laboratory. This isn't as old as the
other cels I'm looking for, but Kitt only appeared
for a few seconds in that episode and Dexter cels
aren't exactly deluging the internet. Also a cel
of any of the Pretty Pony Puff Princesses. (Yes,
gotta keep that trend alive.)

I actually found the *exact* Vampire Hunter D
(original) cel that I was looking for on YJ, so my
VHD collection is pretty much finished. (Now unto
VHD2! *twitch*)

Heh, I am also looking for a cel of Lothar. He was
the best character on that show, dangnabbit! ;)
