Thank you for contacting Mearto with your inquery.
After examining the photographs provided, Mearto specialists have concluded that the subject work is a counterfeit Christian Dior newspaper saddle bag. There are several incorrect essential elements detailed below that allowed specialists to establish this opinion.

The label/leather tag on the interior of the bag should be stitched all around the edges, and also it would be centered so the Christian Dior name is on a straight line and not attached crooked.
The Christian Dior stamp on the back side of the double CD is too narrow and close to the edges.
The piping on the inside of the bag above the zipped compartment is not in a straight line and overlaps visibly.
Unfortunately these descrepancies are signs of your saddle bag being a fake bag. It is very hard to tell the difference between authentic Dior handbags and good imitations however the above mentioned details are some of the areas that are examined.

Auction houses that consign luxury items like Dior handbags will only accept bags of the highest quality/condition, that can be fully authenticated through a physical examination, and by establishing a clear ownership or provenance chain. Therefore, there is no viable auction (secondary) market for counterfeit bags like the subject work.
I am sorry for this unfortunate news.

Please let me know if you have any additional questions. I’m happy to help.
Thank you
