I purchased this B-bag a while ago, at least 4 or 5 years, from a very reputable consignment store. I know they got it from a woman who frequently consigned a lot of obviously authentic items i.e.chanel jackets, etc. --this was when the B bags were first getting hot and I don't think there were many fakes yet on the market, but this bag is so unlike the current B bag, in the years since I've wondered whether it's real and just a very old sort of prototype, or the original fake, fooling the consignor and the shop(Michaels on the UES if anyone knows it). The biggest thing is the leather--it's pebbley, not grainy, it's a nice rich leather but soooo not the typical balenciaga! it did not come with a mirror and the shoulder strap is different as well. If I saw it today on eBay I'd think FAKE but since it's been around a while I would love to hear what those of you who are real Balenciaga histrorians have to say. When did these bags even begin? thanks for helping solve my mystery!
