Oh...a vintage Jumbo in red caviar...I love this red!! I would advise against having an SA at a Chanel boutique look at it. They are not skilled in authenticating (especially not vintage pieces) and for the most part I believe they will turn you away. There is one woman who will authenticate it for you in the Chanel AT thread. Otherwise, I would take pics and for a small $5 fee have the women at etiniceler authentications look at it!! If I saw more pics, I would give my opinion as I have been collecting vintage pieces for a while, but one pic isn't a lot to go on, sorry!! Either way, it is always good to have a second opinion before you make a purchase! Good luck!
