Released in 2011 as a Limited Edition of 1,000 pieces within the Disney Pin-of-the-Month Series, this collectible pin offers a dynamic comparison of two iconic Disneyland experiences with its unique double-sided design. The front side showcases the classic Flying Saucers attraction in polished metal that spins to reveal the Space Mountain attraction behind it, while the reverse features the new Space Mountain at Disneyland Park, where Pluto is dressed as an astronaut complete with a helmet to celebrate the park's evolution. This limited edition collection commemorates significant transitions from Country Bear Jamboree and Winnie Pooh through Golden Dreams, Mulholand Madness, Circle Vision/Astro Blaster, America Sings/Innoventions, Adventures Through Inner Space/Star Tours, Submarine Voyage/Finding Nemo, Flying Saucers/Space Mountain, Swiss Family Treehouse/Tarzan Treehouse, Astro Jets/Astro Orbiter, Mine Train/Big Thunder Mountain, and Mickey Mouse Theater/Pinocchio.
