Hm, we also have the YUA repro lithographs but we 
have yet to see the yutaka one you mentioned (can 
you post a image?). Yann sold the earlier ones of 
the two in uniform in the office and one of the 
two in swimsuits. As for not having a numer 
whatsoever on the lithograph, we'd recommend 
asking Yann as he was part of the interest in 
getting those YUA lithos make to begin with. Yann 
any thoughts? Might not having a number on the 
litho be problematic?
