The Matica slovenská (a mostly government-sponsored cultural, academic, and archival institution) employed Karol Plicka (1894-1987) as its ethnographer, who was able to make documentary shorts from about 1926. He obtained funding from the President’s Office in 1928 to produce an hour-long documentary about village life, Through Mountains and Valleys (Po horách, po dolách). It was awarded a Gold Medal at the International Exposition of Photographic Art in Florence and received an Honorable Mention at the International Venice Film Festival in 1932.
Over Mountains, Over Valleys (1930) is currently not available on any services.
