明亮國際慶典海報上的開心笑臉圖案

A cheerful, yellow smiley face with a wide-open mouth and closed eyes sits smack in the middle of a gradient backdrop shifting from orange to yellow. Above, a world map in soft yellow shades shows off continents. "International Day of Happiness" is plastered in bold black and red text, with "March 20th" chilling in smaller black letters.
