A collection of nearly 80 slides by Witold Koneczny shows the life of the Polish capital in the 1930s as seen through the eyes of an ordinary Varsovian – a passer-by and participant of important events. In addition to images of squares, architecture and monuments, the author photographed military parades, sport events, including the Gordon Bennet Cup in ballooning, and everyday life of the city. Some of his most unique photos include a series of images of the funeral procession of Marshall Józef Piłsudski on 17 May 1935.
