Thank you for posting pics because the seller's pics are not helpful since they are only stock photos. Your bag is authentic. Enjoy!
I think you posted two different sellers though as the ebay link for the Poshmark seller is this one - https://www.ebay.com/usr/maxx3494.
Thank you! I really appreciate it. Whoops, sorry about the eBay link - I think because the item has been sold eBay shows an alternative that is available.
Out of curiosity, what is usually different on the non-authentic Lee Radziwill bags?
