 His landscapes painted in Técső include "Landscape in Técső", "Landscape with Stacks" and "Sunset with Stacks," in which he applied elements of "en plein air" and Impressionism.His self-portrait (1916), held by the Hungarian National Gallery, is considered one of his most harrowing pictures.Encouraged by István Réti and János Thorma, his pupils and friends, Hollósy spent the summer of 1896 in Nagybánya (today Baia Mare, Romania) with his school.
