Anyone know much about Burberry?

Can some one please tell me anything regarding Burberry messenger bags?
I have two...dont know much about them, no numbers, the black one only has that one tag inside, & its made out of pvc, i had received it little over 4 years ago as a gift.
As for the brown one(vyl), I had bought it at the boutique however I assumed information would have come with it, but it didn't. I didn't call the store, because i would have felt silly if they told me..if i bought it there its real.
BTW no auth. cards were received either one of them...assuming didn't come with one.
However one day i was cleaning them out...felt as though there was a piece of paper between the lining & the bag...kind of odd . Has anyone else encountered this before? :s
