I'm probably too late for posting in this thread, 
but here's one of my favourites.  It's nothing 
more than a bunch of backs, which should 
depreciate the heck out of the value (as if there 
would be much value to begin with, heh) but it's 
the only cel I have managed to find of all 10 
members of the extended Team Hokage group (Flame 
of Recca).

You probably can't see the 10th back in this small 
and too dark scan (must rescan), as he's a ways 
down the hall (and a he's teensy rare character 
who I haven't gotten otherwise, for that matter, 
so this lovely back cel is just loaded with 
rarities, heh).
