*The All-Terrain Armored Transport, or AT-AT, was initially visualized (front, by Joe Johnston) as a futuristic tank for Imperial snow troops on Hoth. It evolved into the mighty, four-legged armored walkers that caused great damage to the Rebel base. Eighteen-inch models (back), meant to appear 50 feet tall in the film, were built and used in the most incredible stop-motion animation sequence ever filmed. *Source: Back of card
