Photographs from the exhibition "Colours of Ruins" by Henry N. Cobb. The photographs were made in 1947. Henry N. Cobb came to Europe with a group of American architects as part of the World Studytour education trip, a series of tours though which their participants were to learn about the post-war reconstruction of European cities. The photographer brought home some 100 photographs, some of them are shown for the first time as part of the exhibition in Warsaw. The exhibition is on show until July 28, 2013, at Dom Spotkań z Historią in Warsaw.
