The primary aim of the paper is to analyse the entirety of the first Croatian series of postcards depicting Rijeka, Opatija, Trsat, Sušak, Kraljevica, Volosko, Bakar, and Lovran from 1889 to 1891 and examine their impact on mass printing of photographs, the development of postcards, and impact on the development of tourism. Postcards are understood as integral multilevel hereditary information carriers, which are, essentially, communicators. The main focus is given to the photographers Alois Beer and Ilario Carposio, the printing house Stabilimento Tipo – Lithografico Fiumano, the engraver V. Turati Inc., and other participants in the process of creating postcards. The first analysis is based on the evaluation and selection of old postcards, the second one is based on comparing photographs with woodcuts and halftone printing in printed publications, and the third analysis is based on the comparison of quantitative available data of postcards with the information from the La Bilancia and La Varietà newspapers.
