In 1970, Unclaimed Baggage was set up as a small part-time venture. By the 1990s, however, it had expanded into a full-scale retail store. With the advent of the Internet, even more people have been able to take advantage of Unclaimed Baggage's unusual range of goods.
You will most likely be buying from Unclaimed Baggage. This company now has exclusive contracts to purchase all unclaimed baggage sold on by airlines in the United States. Their retail store is in Scottsboro, Ala. You can also buy from them through their company website or via their store on eBay.
Items discovered in unclaimed luggage have included a suit of armor, the guidance system for a fighter plane (this was given back to the USAF, of course), and a live rattlesnake.
