Can somone tell me if this is 100% Authentic? The person said they got it from an estate sale and they don't have the box, dust cover, or authenticity cards but it looks exactly like the same one at eluxury, including the number of stitches, except that the pattern on the side of the bag is difference above the pocket. These are the pictures of the one on eBay. This is a picture of the bag from eLuxury.com To me, everything looks the same except the side above the pocket, like i said before. Does that matter? Does anyone know if this bag is an authentic Louis Vuitton?
