Both links contain great examples of late 1960s Polish animation. Poland was never a part of USSR.
Moreover, just like Czechoslovakia, Poland did not develop its animation style in a vacuum. They had strong artistic connections with many other European countries, especially France.

Not sure if you are an American... but Europe has a very old and very rich animation tradition. Growing up in Europe I was only vaguely familiar with Disney. The vast majority of animation I watched as a child was European.
they pioneered new techniques in a vacuum, because they were segregated.
complete vacuum is a silly argument, we owe dinosaurs the oil we used to build up our modern societies, would you say that AI would be impossible without dinosaurs?
you paid for it and enjoyed it in the way the artist intended.
> I am training my brain on copyrighted work.
too bad your brain alone is useless.
You need good hands to replicate much of the copyrighted works you "trained" your brain on.
> No artist has developed their style in a vacuum.
some absolutely did, indeed.
Just look at the school of film and animation that artists in USSR developed while separated from the rest of the World.
