You should post this under the "authenticate this" in the LV forum.
FYI:If you found that picture on any site other than eluxury then it was stolen. The photo, I mean, not the bag.
I've seen this color in the denim speedy in an LV boutique, so it could be real. The zipper and handles look authentic as well.However, i've also seen amazingly good fakes , so this could be one of them.
I always wondered if these particular LV's held their shape or do they mush in if not filled. The Denim line is the only LV I ever looked at with a little Lust.
