On April 26, 2006 designers start exhibition-action of black and white posters, devoted to the 20th anniversary of the Chernobyl tragedy. This exhibition is memory about people, who fulfilled their duty with honor. These posters are the dedication to firemen, who burnt in the first night and who threw graphite away from the 4th reactor roof almost with their hands; to soldiers, who worked on the roof of the blown-up reactor without radiation meters, when "15 seconds were enough for each of them for the whole remaining life" (V. Sidelnikov); to the chemical protection service, who manually created maps of radiation fields; to helicopters pilots, who threw graphite and concrete to the radioactive hell, in spite of threat of the hard forms of the ray disease; to academicians of Russian Academy of Sciences, who personally installed radiation meters near the radioactive walls of the power plant; to all the relief workers, who fulfilled deadly dangerous task - relief of radiation explosion results; to all the heroes and victims of April 26, 1986. This is the exhibition-action of actual art about every man's personal response for the surrounding world destiny. It is the exhibition about unity of people, who are able to survive morally in extreme conditions of human-made catastrophe.
