Vertical poster. Top headline: "秋茶会" then directly under it "Autumn Tea Festival". Directly under that: "10月24日–26日 10:00–18:00 / Oct 24–26, 10am–6pm". Bottom: "免费品茗 / Free Tastings". Central illustration: a simple ceramic teapot and cup with steam rising, a few maple leaves drifting beside them, drawn in thin elegant line art. Palette: warm terracotta, soft cream, muted persimmon, gentle sage green. Background: textured handmade paper with subtle fiber grain. Clean modern typography, generous margins, balanced vertical composition. No people, no logos, no other text.
