Movie poster of the day

This rare Tron poster came free in the Los Angeles Times the weekend the movie came out back in 1982. I remember taking it to Tower Records in Westwood, CA. to get it signed by one of the guys who worked on special effects for the movie, Glenn Campbell (not the rock star). He wrote: "Howie, don't de-rezz" in the yellow area in the bottom left corner...  Ironically, that signature has all but de-rezzed in this JPEG. Why Tower Records had the animation compositing camera guy signing autographs and not one of the stars of the film there is a mystery that remains with me to this day...
