Veklenko participated in the cleanup following the catastrophe. That lived experience became the project's moral and creative foundation. From its inception, 4th Block has used graphic design as both artistic expression and civic testimony. Its posters engage with questions of nuclear safety, environmental responsibility, alternative energy, and the human cost of technological failure.

The concerns raised in 1991 remain urgent. The secrecy and militarization that shaped the original Chornobyl disaster are not confined to the past. They persist in Russia’s ongoing attacks on Ukrainian nuclear facilities - acts widely recognized as forms of nuclear terror and environmental warfare. In this sense, the exhibition reminds us that imperial violence and environmental neglect are not isolated events, but recurring historical patterns.

In 2019, the 4th Block Museum was established at the Kharkiv State Academy of Design and Arts, housing approximately 11,000 posters collected over thirty years. The archive ranks among the world’s most significant collections of socially engaged graphic design.
