Partial translation (courtesy OCN):

It is the member cell drawing of [card KYAPUTA 
Sakura]...
* It is not a genuine article. 
Be careful in the case of a bid. 

The image on the page shows the entire cel, 
showing that there is no sequence number in the 
upper right corner.

This dealer is obviously being very careful to 
represent this item accurately.  Those with some 
Japanese can visit this and copy the 
kanji/hiragana that's translated "member cell" 
for reference.
