Hello! I just looked at the link and most of the pictures look alright. There was one picture that was rather blurry - the one which shows the interior patch pocket with the leather patch. I cannot see the font clearly at all (maybe it was the camera flash that caused it). I would recommend asking the seller to email a clear photograph of the font, as well as pictures of the sides of the bag, and a clearer picture of the leather strap (again, I think the camera flash made that picture look a bit too bright, hence slightly blurry).
Oh, I also just wanted to give you a tip: if you have questions about the authenticity of a bag, please post your question in the "Seller Watch" sub-forum rather than the "Louis Vuitton" subforum. That's where the authenticity questions are posted (and hence, it'll probably get you a quicker response time).
