Hi there, I'm new to this forum. Could you guys help me to authenticate this B-bag? Here is the link: http://cgi.ebay.com/Authentic-2005-Caramel-Balenciaga-First-Classique_W0QQitemZ230001324018QQihZ013QQcategoryZ63852QQssPageNameZWDVWQQrdZ1QQcmdZViewItem The seller said she bought from a member of the purse forum. She showed the pictures of a copy of the Balenciaga NY receipt. But meanwhile I also see some people showed the different format of Balenciaga receipt. Also if the leather of pre-fall 2005 collection is still the old leather? Thank you for your help.
