I think the character design is a dead giveaway. :) Cherkasskiy was the only one who drew characters like that, as far as I know. He seems to have had surprisingly few imitators, given the popularity of his films.

This small document certainly helps all of us understand the work of Ukraїnian cinematographers. Including most of the famous products of studio Kyїvnaukfilm (now Ukranimafilm).

Thanks for the link! Interesting, though the text is necessarily short due to the Diafilm (in English, "filmstrip") format. Seems that there might be a part 2 as well, but nobody's scanned it yet.
