Space Mountain pin on poster backing card, one of a series of pins of Walt Disney World Attraction Poster Pins. A Walt Disney Imagineering (WDI) exclusive. The actual pin is the people riding in the spaceship. Pin measures 1.75"x2"; the backing card measures 2.5"x4". Released Fall 2012; a Limited Edition of 300. Mint condition, still sealed in its plastic packaging. I am always happy to combine multiple items in one package to save on postage costs.
