While I did not receive a reply here, I wanted to follow up with what I learned from
Loewe customer service. I described the bag I purchased from Barneys, and my concerns it was a return replaced with a replica, and not caught by Barneys. The Loewe rep assured me the only tag that should be sewn in the interior of this bag is the black tag with the Loewe logo I show in my photos. There is no tag with a serial number or code as I have seen with other Loewe bags on this site. That made me feel much better about my purchase, and I decided to keep this beautiful bag. If you have any doubts about your bag, I would contact Loewe's customer service by phone. While they will not authenticate your bag, they can at least answer questions. Hope this helps anyone who may have the same concerns I did about interior tags.
