Usually an "article not for sale" means that it 
was either a promotional item or a prize, and 
thus wasn't ever available to the public for 
purchase. Like my Psychic Force 2012 watches. 
They were "articles not for sale" because they 
were UFO catcher items intended to promote the 
game -- they weren't sold in a store where you 
could walk in and just buy one. (So the term 
*doesn't* mean that the items aren't included in 
the auction.)

As for possible damage to the cels, they sure do 
look at *least* warped if not worse. The picture 
isn't great, so it would be impossible to tell if 
they'd suffered additional damage from neglect -- 
like line fading or chipped paint. You could 
always leave Q&A for the seller to find out. . .
