Poland’s presence at World’s Fairs between the World Wars is a special issue in that, after a long absence on the map of Europe, the country had the opportunity to show its industrial and cultural achievements in the international arena as an independent exhibitor for the first time. Thus, this event always had a very important political dimension. Its symbol was the Polish pavilion presented in Paris in 1925, but no less important was the pavilion at the New York World’s Fair in 1939. Although it was a success at the world expo, it was overshadowed by the tragic consequences of the outbreak of World War II almost from the beginning. From today’s perspective, it is worth looking at this object, to evaluate its foundation and ultimate significance, as well as to reflect on the difficult concept of national art, in addition to tracing the fate of the pavilion.
