From today, March 10th through March 16th you can purchase your choice of two limited edition Space Mountain shirts.
The design on the left (pictured above) is the design from 1977 by Danny Handke and Vanessa Hunt based on the original attraction poster by Jim Michaelson. The poster on the right is designed by Richard Terpstra based on the 2010 poster by Josh Holtsclaw. There will also be series of drink ware based on the later design. That will be at Disney's Marketplace Co-Op.
