On Saturday, November 19, 2022, two lectures were held at the Foundation. They were part of the post-graduate studies of Modern Art History at the Polish Academy of Sciences. Pola Dwurnik gave the first lecture on the growing catalogue raisonnee of all artworks by Edward Dwurnik. The second lecture, delivered by Daniel Ożga, was about lithography – Dwurnik’s favorite graphic technique. After the theoretical part there was a lithography workshops, during which both speakers made a special lithography print – a collective portrait of the gathered listeners. We would like to thank dr Natalia Kaliś for including us in the study program.
