From the auction:

"All sheets are state-of-the-art copies from a 
not for sale master that's hard to find even in 
Japan (the master was bought on a japanese 
auctions home page), given to Tokyo Movie 
Shinsha staff members only, so their value for a 
true VERSAILLES NO BARA fan is PRICELESS!"

Yep, sounds to me like it's a photocopy the 
seller made himself/herself to sell for profit.

I've lost any interest I once had in photocopied 
sketch sets/storyboards simply because it's so 
easy to make more copies of them (or scan & burn 
to cd) and sell/auction/give them to everyone 
and their brother, as is happening in one anime 
fandom I follow. >_<
