Hidroavião na ilha · Pôster de viagem mid-century

Retro vintage poster artwork of a seaplane landing on turquoise water beside a tropical island, as a mid-century travel poster with flat gouache shapes and sunny colors. Bold simplified shapes, a limited color palette, halftone texture and aged paper grain, strong graphic composition. Purely visual: no text, no lettering, no numbers, no logos. Vertical 4:5.
