Credit to @puz for the 1981 model.
and myself to change the screen.
Note: Fake/Fanmade.
Note 2: Only the "1979 fanfare" was used from 1981 to 1993.
I don't own 20th Century Studios (then known as 20th Century Fox) and it's trademark fanfare.
(I did not copy, it is inspired by Victor, and some others)
