The National Museum in Krakow presents the exhibition Marian Warzecha. Open Set at the Józef Czapski Pavilion. The 90-year-old artist, co-founder of the Second Kraków Group, is one of the most important and fascinating conceptualists in Poland. He has been presenting his original take on the creative links between art and science for decades by documenting his reflections on the meaning of life and art, always staying faithful to the idea of maximum substance from minimum means of expression.
