I second jmc3007's advice to have this bag authenticated. Celine is faked so often and so 'well', the Luggage especially so. Read the reviews before choosing the service, though. Not everyone who claims they know a brand is actually good at authenticating it.
I was in the middle of requesting authentication from Real Authenticators and had the good sense to look for reviews. Here at tPF, a lot of people have had poor dealing with them. That's when I found this thread (I apologize if I've highjacked it) and lead me to call Celine.
Now I am back to square one. I think I should get it authenticated, and I also don't know that I will trust the authenticators. That would leave me, back again, at square one.
