Does anyone know whether it is true that the snap on the wallet attached to the St. Louis PM bags always matches the color of the bag? I have seen a yellow bag that I am fairly sure is authentic, but it has a silver snap (the photo was posted here in the thread "calling all goyard fans") and I have been told that Goyard claims that the snaps are never silver -- always the same color of the bag. Could this be incorrect? Does anyone know if there are authentic PM bags with silver snaps? I'd really appreciate help with this if anyone knows the answer.
