Jojo21, I am sure this bag is authentic, but because it is so rare, I want your opinion too. This is truly a one of a kind and I am thinking of selling it so I want to be able to say it was authenticated here on the purse forum, because I know folks will question the authenticity because it's the ONLY ONE!! I can not find another one like it! Thinking it is from a limited edition or was used as a runway bag. I am having a hard time deciding if should sell or keep it. Tell me if you agree with me about authenticity. I know it is an older model because of this lining, but this IS an official MK lining, I am sure you have seen it before as well. Here are the first four pics and I will put more in a following post. Can you believe this bag?? I'm blown away by it! It is a combo of the Uptown Astor and Mosley Tote! I have never seen this and am thinking it's from a limited edition. I googled it and could not find anything about it!
