A promotion of the book »The Hungarian Maritime Trade History of Fiume (1868-1918)« by Márton Pelles and Gábor Zsigmond was held in the representative premises of the Hungarian Institute in Zagreb (Zágrábi Magyar Intézet) at the Europe Square in the very center of the city. The two Hungarian researches published a Hugarian and English bilingual detailed study of Rijeka shipping during the Hugarian administration, researching in the Rijeka and croatian archives, as well as in the rich hungarian archives, disovering numerous interesting facts on the development of Rijeka.
While working on the manuscript, the authors kindly provided HZD president Heimer with rich materials on shipping flags they found in the archives, and in response he provided them with a series of illustrations of these flags for the published book.
