I am looking at a Damier Chelsea Bag. The last 3 letters of the date code are 997, I beleive that means July 99? My question is the Damier lining is brown. I know it is now red/orange and was originally a brown canvas lining. When was the Chelsea done in brown canvas lining? How can I check authenticity? Are there any pictures I can see for the chelsea bag form 1999? Where to look at what the Damier would look like where the louis Vuitton would appear on the Damier canvas outside. Where the serial number would be. Also pictures of how the seams on the side and on top with zipper closed,etc. Thank you.
