Taiwan, also known as the "Beautiful Island of Formosa," is a nation rich in cultural heritage, abundant natural resources, and distinctive urban architecture. This project, themed "Source of Culture, Infinite Charm," consists of a series of six posters designed to promote Taiwan's tourism. The images in the posters capture the natural and architectural features of six Taiwanese cities, transforming them into visual elements of the poster design. By utilizing and harmonizing cultural colors, the project aims to express both the modernity and the traditional cultural essence of Taiwan's cities.
