I paid just over $1000 for this cel (with no 
sketch or background) about this time last 
year... There seemed to be a lot of Heero cels 
from the second OP around at one time which 
varied in quality (from full face to just his 
hair - if you've seen the second OP you'll know 
what I mean). I've never seen a Trowa one 
either. Hope you find what you're looking for!
