The long story short: this is the 1979 copy of the Star Wars (pre-ANH) distributed in Poland (yeah, with subtitles). After the licence expired, all prints were to be officially destroyed (burned) except for one kept for National Film Archive. But one of the commissioners swapped one of the copies by putting the reels of another movie into the tins, thus saving a vintage ANH print 😃

Can we call it a Star Wars preservation effort… from 1980s? Or a 3,3 kilometers of film history? 😉
