Thank you! It's just I bought a 1995 Kelly, it doesn't have it. So I'm not really sure if it's 100% authentic. It was from a very reputable website tho....As I stated previously, all Hermes bags have them. Bags from the 40s have these stamps. Here and there maybe a bag escaped stamping, no one knows why, but 99.9% are stamped.
This information is readily available across the web; not sure what else you are looking for here....
