Space Mountain anniversary t-shirt available for a limited time

Forty years ago this week, something happened that would thrill sci-fi fans for generations.

Space Mountain opened at Disneyland.

Oh, you thought we were talking about something else? Maybe the premiere of Star Wars? Well, that’s understandable. Star Wars changed the world May 25, 1977, just two days before Space Mountain took off in Disneyland for the first time. Coincidence? We think not.

Disney is marking the anniversary of Space Mountain with a limited-edition t-shirt for adults ($29.99) and kids ($22.99). The two-sided design is available until Sunday, June 4. Allow 3-5 weeks for delivery.
