While not immediately connected to Oregon cartooning, Czech animation might have had influences in the fields of stop motion animation. You be the judge after watching this short and free course “Introduction to Czech Animation” by UK-based scholar Adam Whybray, author of The Art of Czech Animation.
“This introductory primer to the History of Czech Animation is perfect for animation scholars and students, especially for those with an interest in some of the most inventive and formally beautiful stop-motion animations of the last one hundred years. Practitioners should find the recommended practical exercises at the end of the lessons inspiring, while history students will appreciate the rigorous socio-historic contextualisation that covers Nazi occupation, Czech Communism, the Prague Spring, Normalisation, and the Velvet Revolution, to the present day. Fair use clips and illustrative examples are combined with slides and lectures.”
