Well, I did not say : "Those beautifully designed posters are not Turkish, they are Yugoslavian."
Actually, if you want to know design is not Yugoslavian, or Turkish...
Sound of Music is just a copy of US R73 insert:
Snow White is copy of R70 British quad:
"Beautiful" Tarzan And The Brown Prince is Italian design:
And so much hilarious Los monstruos del terrorr is actually copy of German poster design:
Also, when you see: "Croatia Film" or "Makedonija Film" printed on the poster, It might be a clue that poster is printed in Ex-Yugoslavia, not in Turkey.
I would feel that is not very logical to think that poster with "Tasmania Film" on it, is actually printed in Turkey. But, hey - who anyway read that.
So there you go, you have learn something here.
