A thought-provoking exhibition delving into the complex realm of border art, a form of artistic expression challenging societal divides. Borders, human-made constructs, wield the power of exclusion, which bolsters the idea of defining the 'other.' Artists responding to this theme birthed border art, focused on, against, and in the face of such divisions. The exhibition, titled "About Sharing..." showcases contemporary and 19th-century works examining national borders amidst modern migration challenges. Highlighting the Polish-German border's intricate history, the display evokes collective memory and encourages rethinking borders not merely as dividers, but as zones for exchange and interaction. Diverse media and interactive projects amplify the exhibit's resonance, transcending museum walls to engage the community of Poznań.
