They are reproductions but the sellers have not 
listed as such.  

ebay item 1011230831 is a cel of Urd that was 
discussed on July 1st (search for Jim W as 
author).  One difference (of several) from the 
video frame is provided in a picture in that 
post.  

ebay item 1012533962 is shown below on the left, 
with the comparable cel from my collection that I 
believe to be the production cel (in which all 
the details seem to match what I see in the video 
frame).  The green arrows point out differences 
from the video in the ebay item (a white area of 
the dress that should be colored, and an area of 
the necklace that is missing a shadow).  

A reminder, repros appear to be limited to cels 
from the AMG OVAs, and it is wise to check the 
authenticity of OVA cels for yourself by 
comparing them to the source material (i.e., I 
haven't checked all the OVA cels currently on 
ebay, but I would if I were interested in them).  

On the other hand, I haven't seen or heard of any 
repros from the AMG movie (so bid away on movie 
cels).
