"A poster inspired by the song What a Wonderful World. The design is composed of small images capturing scenes from the song: in the top left corner, a landscape with lush green trees and blooming red roses; next to it, a clear blue sky with soft white clouds. In the top right corner, a serene starry night with a full moon shining brightly, evoking the phrase 'sacred night.' At the center, a vibrant rainbow stretches over a peaceful landscape. Below, children happily playing in a park, and elderly friends chatting under the shade of a tree. The color palette is rich, conveying warmth, hope, and gratitude. The words 'What a Wonderful World' appear in the center in an elegant, classic font, harmoniously tying all the images together."
