Well, it's not a cel, but...erm...MTT OAV cels 
are a bit too expensive for me, 'specially of 
Aburatsubo...so here's a sketch :D This is a 
hilarious sketch of Aburatsubo from episode 4 of 
the OAV, reacting to Sae's offer to go with Takeo 
to the party (as the entertainment). As you can 
see, he's less than thrilled, complete 
with "dame" ("stop!") written on his head...
(there's another sketch that goes with this 
that's more complete...but this one is so much 
better :D)
