This is a turquoise chaser pin featuring one of the cups from the Mad Tea Party. We see a Mickey icon on the top right. The pin is shaped like a cup.
The reverse of the pin is silver with mickey heads. On the back of the pin is written " ©Disney Made in China Hidden Mickey Pin 8 of 10". There is a Disney Pin Trading Logo on the rear of the pin. One post and one nub can be found on the back of this pin.
