Does anyone know where I can find one?
This one looks pretty good to me if you don't mind ebay:
eBay: Marc Jacobs Goat Skin Purse Handbag Made in Italy (item 130029674877 end time Sep-27-06 19:11:10 PDT)
isoldit is generally reliable, and the leather looks good to me.
I saw a SMALL black patent bowler tonight at the Bloomie's at Fashion Island, Newport Beach.
