I think the oldest is from 1963 "Les Oiseaux" / "The Birds".
Surprisingly, this is probably the only one from the 60s but I did not check all the dates yet.
Among them we also found titles like:
-American Graffiti
-Nosferatu (Werner Herzog)
-La Guerre des Étoiles / Star Wars
-Silent Running (English poster)
-Metropolis (from the 80s)
I will try to upload some of them, soon.
With kind regards, Corrado
