This year is the 30th anniversary of the original Star Wars movie and to celebrate this occasion, Lucasfilm Ltd. and Gen Con are organizing Star Wars Celebration IV, which will be the largest Star Wars event ever. This 5 day event takes place May 24-28 at Los Angeles Convention Center.
To celebrate the 30th Anniversary of Star Wars, Lucasfilm Ltd. and Gen Con LLC will throw the largest party ever for fans of the saga, taking over the entire Los Angeles Convention Center in May 2007 for five days filled with live entertainment, celebrities from all six movies, special film and video presentations, an exhibit of movie props and costumes, exclusive merchandise sold at a 24-hour-a-day store, pop culture tributes, immersive events, costume contests, and scores of additional activities.
The US Postal Service will be releasing their new series of Star Wars postage stamps during the event on May 25th. The stamps will feature 15 different stamps on a single sheet and voting is currently open on Jedi Shipping and Mailing Master to decide which stamp will be issued on a single sheet.
