A throwback homage to Mickey's earlier days as Steamboat Willie - the first Disney cartoon to feature synchronized sound. Collect this pin to commemorate a very special moment in history. Embark on a pin trading adventure and exchange some of your designs with fellow fans or Cast Members! The telltale signs that a pin is tradable are if it's metal, bears a ''(C)Disney'' mark on the back and represents a Disney Event, Place or Location, Character or Icon. You can exchange a maximum of 2 pins per Cast Member, per day-but make sure it's one that's not currently displayed on their lanyard to keep the trade fun.
