In the decades after the war Bihalji-Merin published a number of books promoting Yugoslav cultural heritage, especially on the topics of naïve homegrown artists like Ivan Generalić, the medieval Bosnian stećak tombstones as well as abstract painters such as Vangel Naumoski. He was a member of the international experts commission which organised the Fifty Years of Modern Art exhibition and is credited with securing unprecedented exposure for Yugoslav art at the 1958 World Fair in Brussels.
