The flyer is advertising a summer sailing event hosted by the Sailing Club Nha Trang for people over 16. It will include the event slogan, time, artists, price, location, and website. The focal point is a mermaid enjoying music under the sea to represent the beautiful sea and music, using her face to attract attention and stimulate curiosity. The largest text is the slogan in the second largest font on a neutral colored underwater background to make the text and arts stand out.
