Thank you for contacting Mearto with your appraisal inquiry.
It is a beautiful handbag. 
However after having examined the photos very carefully we have come to the conclusion that it is not an authentic Louis Vuitton handbag.

The way the logos on the leather has been placed in the design of the bag is not the way an authentic Louis Vuitton handbag would look like. The LV logo must be placed in the center on all sides of the bag and never in the lining. This is the case with your bag on the end where the logo is halfway in the lining and on the side where the logos are half-hidden behind the zip pocket.

This is one of the crucial points when determining if it is an original Louis Vuitton bag. We have also examined the leather and the stitches on the photos and again the quality is not quite the usual high Louis Vuitton quality of leatherworks and colour of the stitches.
The sentimental value it represents to you will be much higher than the market value.
I am very sorry for the unfortunate news. 
Please let me know if you have any additional questions. I’m happy to help. 
Thank you
