I also have a keychain that is a series of four highly laminated plastic cards riveted in one corner (with the chain coming off this rivet). You can spin the cards on the rivet to unveil one of the cards below. Each of the cards has an image from Return of the Jedi on the front and back. Never seen anything like it before.
My last thing is a Yoda pendant on a necklace still carded on an original (albeit beat to hell) ROTJ red card.
I love these three things.
