Ok so I came across a Key Holder thats vintage from the early 90s- date code checks out. But on the inside it, the heatstamp, there is nothing after "Louis Vuitton". Just has Louis Vuitton, made in Spain is underneath the little flap and on the metal part where Louis Vuitton is engraved there is an R with a circle after it? Is this authentic? I've never come across with this before. HELP!
