In Bulgaria, Jaroslav Věšín became part of the organized art life. In the spring of 1898, he took part in the Third General Art Exhibition in Sofia (1898) with works from his Munich period, and five created in Bulgaria, including “Threshing”, today, within the collections of Sofia City Art Gallery, featured in this exhibition. He was a member of the established in 1903 “Contemporary Art” cluster that brought together architects, artists, and writers seeking new modern forms of expression, and, since 1904, presented his paintings within the cluster’s exhibitions. He was included in the international shows of Bulgarian artists: the art and industry expos in Paris (1900), Saint Louis (1904), Liege (1905). In 1904, he was among the founders of the Union of South Slavic Artists “Lada”, with representatives from Bulgaria, Serbia, Croatia, and Slovenia. In 1905 he was elected as chairman of the Bulgarian section, and a year later – as honorary chairman.
Jaroslav Věšín had long ceased to be perceived as a foreigner. His paintings on the pages of history and art textbooks still accompany generations of Bulgarians. He exerted extraordinary influence on late 19th–early 20th century Bulgarian art and painting. His champion were people – in the field, in the markets, and in the war. His subjects came from different social strata – vivid, with distinct individuality, memorable. In his works – from the compositions treating hunting scenes and the customs of the Slavs, to his military art canvases, open an art world of tints, faces, and heroes, born from the vivacious and vibrant spirit of an artist for whom borders were not a state of mind.
