This project is a project that presents the concept branding of 'Hyundai Dream Ball Park', the largest baseball stadium to be built in Gijang, Busan, and focused on establishing BX and BI and applying the Flexible Identity System to deliver various information and images. The motif of the identity is FI, inspired by the structure of the stadium being built and various harnesses thrown by the pitcher, so that various baseball symbols can be drawn. The biggest feature of this identity is that Symbol can relay and introduce information, weather, and team marks of various games. Also, the symbol and typeface were made to look as simple as possible, and to avoid monotony, point colors and baseball were expressed in wit with a period.
