I think i've noticed this seller selling other AMG 
OVA cels.  Bell in a brown dress, i think, which 
he's sold multiple times...i don't have the urls, 
sorry.   I think He/she also has another ID 
used as a front to sell the cels. 

I haven't ID the SM cel with the eps yet, but  
just looking at it, her nose looks a bit crooked 
and the lips seem too curvacious for Black 
Lady.  Also, no sequence holes..? (not that 
lack-of-holes is full proof  for spotting a fake)
