Gold Prototype of Pin 26300. Carting such "toys" as a cage, a spiked club and a steel trap, the mischievous trick-or-treater Shock is spotlighted on this diabolical gold-finished pin prototype, which preceded a limited edition of 250 black-metal pins based on Tim Burton's The Nightmare Before Christmas. Developed exclusively for Disney's Purchase It Now Store at DisneyAuctions.com, only four of these gold-finished prototype pins were produced. MATERIALS: hard enamel. Shock is dressed in a purple witch's dress and hat, with a white face and blue eyes and lips. There is a yellow rope around the cage. She is smiling with pointed teeth. SIZE: approx. 1.25" W x 2" H. SKU = DA09788. A Certificate of Authenticity accompanied this pin.
