I don't really know a great deal about LV, but I am selling a pochette tikal that my mother gave me. and i have a bidder asking for the date code? i don't even see one though... or a heat stamp but i know this is real unless the san francisco bloomingdale's is selling fakes now... because i was there when she bought it. The only thing I can think is that the smaller purses don't have them. I know on the larger ones theres that leather patch that has the # on it... but all that's inside is that R sign and it say Louis Vuitton Paris made in France where do i find these things?? or at least something that i can tell her or take a picture of that shows authenticity? here's some pictures i took of it.
