This is the one the counterfeiters are trying to duplicate in the photo above. Notice there is no sharp contrast and that the signature blends into the color of the fabric. It is also not super shiny. Has a bit if a sheen, but very subtle. If it appears overly shiny, that is a good indication it is fake.
Here is an authentic lining that was used on many older MK bags. Again notice that the color of the logo is subtle against the same color as the material. There is never a sharp contrast.
