help with eBay Mulberry Authenticity

  1. Im a newbie to this site and cant find anywhere to authenticate a mulberry i want to buy so i thought this might be the best place to ask.

    i was wondering whether this was to good to be true - a mulberry brynmore for £140? probably the cheapest stylish way to deck out a beau ever?! thanks for any help you can provide!
