Illustrations by Květa Pacovská for Jak Se Hraje Na Dvere a Jine Muzikantske Pohadky (roughly: How to Play on Doors and Other Musical Stories) by Ilja Hurnik (Prague, 1973):
Marina from Ukraine (visit her on last.fm) contributed these illustrations by Alexandr Mychajlow for Fairytales of Foreign Writers (Ukraine, 1988). I can’t find any info on the artist.
