BUENOS AIRES.- Fundacion OSDE opened the exhibition, Invasion 68 Prague. The show is comprised of images personally selected by Josef Koudelka from his extensive archive, and is co-produced with Magnum Photos. Conceived as an installation it features large-scale, ink-jet prints as well as related texts. In 1968 Josef Koudelka was thirty years old.
