Well...In the beginning...Many years ago on Y!
J...I personally won 2 sets of FAKE OVA cels, & 
then won an auction for a single cel.  I Only 
kept 2 out of the 2 sets & then sold the rest on 
E-bay.  Up until a week ago...Those were the ONLY 
FAKE OVA cels outside the ones I had originally 
bought that I have EVER seen for sale.  

I'm pretty sure the studio didn't release them 
outside of ones that were either stolen, or given 
out as gifts.

I have 2 remaining in my personal collection...I 
sold one of them to the lovely celmansion.com =)~!

These cels are next to impossible to find...The 
RARE of the RARE...Even in anime cel collecting 
as a whole.  I hope this helps, & I wish you luck 
in trying to find them ^^;!  You'll most likely 
be up against a LOT of competition amongst us 
YAOI fanatics ^^;!
