Help with vintage chanel bags!!!

  1. Hi everyone! first time poster, but ive been looking at this forum for awhile now.

    i need an expert. ive googled this but there are no guides about vintage chanel

    specifically: (but any info is welcome)
    a) how do you spot a vintage fake?
    b) what does the sticker inside a vintage chanel look like? and does the hologram card look the same as now?
    c) specifically talking about flap bags, has chanel ever made it so that the stitching on the edge of the flap IS visible? I know usually the flap bags have stitching on the edge that isnt visible when you look at the face.

    example: [​IMG]
    non visible stitching on edge

    Thank you!
