This is a graphic design project for the special exhibition Gyeonggi, How Is It!, held at the National Folk Museum of Korea. In line with the exhibition's focus on the topographical context and cultural value of Gyeonggi-do, the visual form of 'contour lines' representing terrain was adopted as the primary design concept. The spatial characteristic of Gyeonggi-do—connecting in all directions—was reconstructed into a multifaceted three-dimensional structure and seamlessly integrated across posters and invitations. The interplay of linear contour elements and three-dimensional depth intuitively captures the interaction and spatial flexibility of Gyeonggi-do that the exhibition aims to convey.
