"Forty years ago this month, a special ceremony hosted during the annual July 4th Company Picnic in 1981 sought to commemorate the establishment of Skywalker Ranch itself, which would soon become the official home of Lucasfilm once new buildings finished construction. To officially herald in this new era for Lucasfilm, and to celebrate the company’s 10th anniversary that year, a time capsule was placed into the cornerstone of the Main House building containing several mementos and artifacts representing Lucasfilm’s cultural and merchandising legacy up to that point."
