vintage louis vuitton

I received this bag as a gift a few years ago and wanted to double check its authenticity as I was thinking of maybe selling it. I could not find a date code but the quality of the bag seems to be pretty good. Please let me know what you think.

I have recently been gifted a variety of vintage Louis Vuitton bags. I am unsure whether they are real or fake as most do not have date codes. The lining of this one is of poor quality and the stamp's stitching is questionable. I would really appreciate your help in verifying whether it is real...
