About 3 years ago or so, I purchased a small box of new old stock automobile keychain / keyrings / fobs at the auction/sale of Mr. Bill Miller, renowned car collector and memorabilia collector, current owner of Carlisle Events and former owner of several automobile dealerships.  

I'll be listing them all today in individual ebay auctions/sales.  

All are stamped on the back, B-E Industries Stamford CT.  That was a novelty company that made these sort of novelties in the 1970's-1980's.   Technically NEW OLD STOCK, but cheap plastic being what it is, they will show scratches and general wear, from bag storage  etc. etc.  

Regarding shipping:  I DO NOT CONTROL THE PRICE OF SHIPPING.  EBAY REQUIRES ME TO PROVIDE A TRACKING NUMBER TO PROVE ON TIME SHIPMENT  AND TRACKING CAPABILITIES.  The little box that I use to ship probably weighs more than the keychain itself.  I use the cheapest shipping method available, which is called USPS Ground Advantage.  

If you buy more than one, the shipping will be free on all additional keychains.  If ebay charges you multiple shipping fees, I'll refund it when I generate the label
