Yes, to be sure we would need all the necessary pictures.
Without them, the best I personally can say is: there's nothing that stands out to me on this one either. If you cannot get additional pictures and the place you're purchasing from has a good return policy, I'd say you can purchase the bag and get it properly authenticated when you receive it. Are you sure there's no way you can contact the seller and request all the pictures?
Thank you both so much for your quick answers. I will try and get the pictures requested, but not sure I can get them.
