I have to agree with Twisty, much as I hate to. 
Heh.  I would love to say that my absolute
favorite cels will NEVER leave my collection, but
the fact is that there are a few other things in
my life which I love far more (my hubby, my
family, my cats), and if, say, one of them
incurred huge medical bills or something of that
drastic nature, I'm afraid the cels would fly like
autumn leaves.

In the absence of any horrible emergencies,
however, I cheerfully predict that there are
several cels and production sketches which will be
piled on top of my dead body someday and buried
along with me.  ^_~  'Cause otherwise, I'd have to
HAUNT whoever bought 'em from my estate...

Since everyone here has seen eyes-open Rezo,
cyber-Harry, nekkid pan Gawl, and Carrot in Zaha's
cloak toooooo many times... *embarrassed grin*...
I'll post one that I only just received this week.
 I have so got to update my website!

From my current art obsession, RahXephon,
this lovely thing is an A1end pan.  Mmmmmmmmmm...
