Hi, I'm looking for this bag below, but in black leather. I know they used to have it in gold leather in the store. Does anyone know if they still make it in black leather and how much is it? I can't find it on the Gucci website Also, do you think this bag is authentic? http://cgi.ebay.co.uk/GUCCI-137385-BN-100-AUTH-D-RING-MEDIUM-TOTE-BAG-PURSE_W0QQitemZ5472358115QQcategoryZ15729QQtcZphotoQQcmdZViewItem Thanks!
