Not much art was produced during the World War II in Yugoslavia, with mostly partisan graphics being preserved. After the war old styles and techniques persisted until esthetic utilitarism and social realism were introduced with the new socialist system. In 1950s new avantgarde and fantastic elements emerged once again with the esthetics of shock. In the time of SFR Yugoslavia no single dominate style existed with many new institutions and societies being formed in Ljubljana, Zagreb, Belgrade and other bigger cities. Special phenomenon, recognized also abroad, was self-taught naive school in Hlebine with Ivan Generalić. On the other side academic approach became prevalent, forming many courses and experimenting with geometry, magic, colors, photographic realism and other elements. The most famous groups were "New tendency" from Zagreb, "Group 69" from Ljubljana and "December" from Belgrade. Famous artists of this period include Miodrag B. Protić, Branko Miljuš, Miljenko Stančić, Vladimir Veličković, Vjenceslav Richter, Ivan Picelj, Miroslav Šutej, Janez Bernik, Jože Ciuha and Adriana Maraž. Along with painting there was also a huge flourishing of graphics, while sculpture in SFR Yugoslavia was less diversiform and mostly soc-realist, resembling Yugoslav architecture.
