He also studied at the Academy of Fine Arts, Munich, and began to develop his own version of expressionism and cubism in Croatia, with refined colour harmonies.
In his later work Šulentić painted religious motifs, landscapes and city views, but he remained foremost a portrait painter.
"[1] He attended high-school at Karlovac,[2] then in 1910 took classes given by Robert Auer at the Provisional School for Arts and Crafts in Zagreb.
[4] During the period 1921-1927 he exhibited with the Independent Group of Artists (Grupa nezavisnih umjetnika) whose other members were Ljubo Babić, Vladimir Becić, Jozo Kljaković, Frano Kršinić, Ivan Meštrović, Jerolim Miše, Marin Studin and Vladimir Varlaj.
[4] Impressions from these trips were recorded in sketches and watercolors, with a series of notes which were later published in his book "People, Places, Infinity" (1971).
[1] At the age of 54, he found himself retired on a small pension at a time when there was limited opportunity to exhibit and earn a living from art.
[6] In 1930 on a trip to Paris, he painted one of his best pictures "Place de Tertre", using a limited colour palette, and creating a modern sense of space.
[4] Šulentić was an important figure of the second generation of Croatian Modernism, the creator of a series of iconic works in his own signature style.
At the end of the sixties he was a master of expressive colour and portrayed in-depth content in human, painterly gestures.
