This bag isn’t that old. If the seller pulls out the lining of the interior zippered pocket there should be a serial number. That being said, I don’t see any red flags so far, so the risk is yours to take.According to the seller & I quote "From the 60's to early 70's Fendi S.A.S. did NOT have a serial number, most had a metal tag. " Therefore this bag does not have a serial number tag inside the zippered lining. Is there another way to view the pictures and tell if it's authentic?
