Doug Saito calls them Trinkets. There are old ones, and there are newer ones. Here's one from the Venetian that will be part of a series. Venetian likes to do invitational themed slot tournaments. They have the "Festivals of the World" that goes on all year, and just started a "Route 66" series that does a different city and sub-theme each month. Last week was Chicago, and "Luck of the Irish".

Here's the key-ring that was a player favor. As Orphan Annie used to say on the radio "Be the first kid on your block to collect them all"!

Start in Chicago and end in Las Vegas. Next month is St. Louis and "Gateway to the West" which will likely feature a trinket with the Gateway Arch on it. Others are Tulsa, OK City, Amarillo, Santa Fe, Albuquerque, and Flagstaff. Last event features Las Vegas in December (even though it was not on Route 66).
