In a story over at Digthatbox.com, a Star Wars fan describes just how he found the autograph of a camera assistant in 1965, George W. Lucas Jr. Here's a quick snippet.
"However finding the screen credit was only the beginning of the adventure. Tom continues: "Once I found the credit I immediately wondered if Mr Lucas had signed a contract. Or maybe there was something else in the archives with his signature?" Tom informs me that during this time the Family Theater building was going through a lot of renovations, and much of the company archives were headed to the local dump. "I had to act fast, so I frantically started looking through every bit of paperwork. I spent every lunch break I had looking through the archives." Unfortunately for Tom his efforts were in vain. After months of searching he gave up hope. Until one day fate pushed him in the right direction."
