Postmodern Children is an exhibition catalogue design project for the Museum of Contemporary Art Busan (MOCA Busan), reconsidering the conventional view of children as subjects of enlightenment and embracing diverse forms of being. Breaking away from rigid modernist perspectives, the exhibition explores multifaceted aspects of childhood through various artworks. The design identity is built on a visual rule where the orders of children and adults coexist. By layering adult exhibition content over spontaneous doodles drawn by children, the catalogue visually reflects a horizontal relationship built on mutual acknowledgment.
