He had a dream to exhibit his paintings in Kremenets and Vinnytsia as well as in Poland. As a connoisseur of Polish and Ukrainian culture and history, Kropyvnytskyi  studied the monuments of Ukraine. Together with his daughter, he visited cities and villages as well as castles and fortresses connected with the history of the Polish borderlands.
